Subject: [PATCH 05/24] Add workflow to reproduce issue #7
 (WindowsAttachProvider could not be instantiated)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three-job workflow (layout-probe → reproduce-windows-attach-dll →
workaround-sanity-check) that confirms the ServiceConfigurationError on
JDK 8 Temurin when jre\bin is stripped from PATH, and verifies the
-Djava.library.path workaround. Triggered via workflow_dispatch.

Subject: [PATCH 07/24] Update workflow: assert fix works instead of unfixed
 behavior
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fix is already present in AttachHelper.java — tryLoadLibrary() finds
attach.dll relative to JAVA_HOME and prints "Loaded attach <path>".
Update Job 2 assertion to verify the fallback fires and no
ServiceConfigurationError appears when jre\bin is stripped from PATH.

Subject: [PATCH 08/24] Fix assertion and add reproduce-without-fix job
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Job 2: updated assertion handles both cases — fix fallback fires
  ("Loaded attach" present) or JVM finds attach.dll via
  sun.boot.library.path (no fallback needed, no error)
- Job 3 (new): reverts the loadAttachLibrary() guard in source,
  also strips sun.boot.library.path of jre\bin via JVM flag, then
  runs the unfixed jar to attempt a conclusive reproduction of the
  ServiceConfigurationError
- layout-probe: also prints sun.boot.library.path for diagnosis
- workaround-sanity-check: now runs in parallel with Job 3 (both
  depend on verify-fix passing)

Subject: [PATCH 09/24] Rework library isolation: use JVM flags instead of PATH
 manipulation

Replace the unreliable GITHUB_ENV PATH-stripping approach with direct
JVM flags:
  -Djava.library.path=.
  -Dsun.boot.library.path=.

Setting both to '.' (current dir, no attach.dll) forces
System.loadLibrary("attach") to fail, without touching the process
PATH. This makes every job step self-contained and reliable.

- verify-fix: fix's tryLoadLibrary() finds attach.dll via JAVA_HOME
  absolute path; "Loaded attach" must appear
- reproduce-without-fix: remove loadAttachLibrary() guard, same flags,
  assert ServiceConfigurationError is produced
- workaround-sanity-check: explicit -Djava.library.path=jre\bin with
  -Dsun.boot.library.path=. confirms the manual workaround

Subject: [PATCH 10/24] Use reflection to null ClassLoader.sys_paths for
 reliable library path isolation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous attempts to override sun.boot.library.path via -D failed because
the JVM overwrites that property at startup after -D arguments are processed.

New approach: inject a reflection snippet into the test code that nulls
ClassLoader.sys_paths and sets sun.boot.library.path="." at runtime.
This forces the next System.loadLibrary("attach") call to re-initialise
both search paths as "." (where attach.dll is absent), faithfully
simulating an environment where jre\bin is absent from all search paths.

- verify-fix: snippet injected into loadAttachLibrary(), fix fallback fires
  → "Loaded attach" must appear
- reproduce-without-fix: snippet in list(), loadAttachLibrary() removed
  → ServiceConfigurationError must appear
- workaround-sanity-check: same as above + -Djava.library.path=jre\bin
  → usr_paths finds attach.dll, no error

 name: Verify Fix for Issue 7 - WindowsAttachProvider could not be instantiated
 
-# Strategy: instead of manipulating PATH (unreliable across steps via GITHUB_ENV),
-# we control the native library search by setting java.library.path and
-# sun.boot.library.path to "." (current directory, which has no attach.dll).
-# This forces System.loadLibrary("attach") to fail unless the code explicitly
-# loads it another way — exactly what the fix in AttachHelper.tryLoadLibrary() does.
+# Root cause of issue #7:
+#   ClassLoader.loadLibrary() searches sys_paths (from sun.boot.library.path) FIRST,
+#   then usr_paths (from java.library.path).  On JDK 8 Temurin the JVM always sets
+#   sun.boot.library.path = jre\bin at startup (overriding any -D flag), so
+#   System.loadLibrary("attach") always succeeds via sys_paths.
+#
+# To isolate the failure we:
+#   1. Pass -Djava.library.path=. so usr_paths = ["."] (no jre\bin).
+#   2. In modified source: null ClassLoader.sys_paths via reflection and set
+#      sun.boot.library.path="." so that the NEXT loadLibrary call re-reads both
+#      paths as ".".  This faithfully simulates Oracle JDK 8 or any environment
+#      where jre\bin is absent from every search path.
+#
+# Three jobs:
+#   1. layout-probe           – informational, no assertions
+#   2. verify-fix             – fix fires fallback, "Loaded attach" appears, no error
+#   3. reproduce-without-fix  – no loadAttachLibrary(), same isolation, ServiceConfigurationError
+#   4. workaround-sanity-check – no fix, but -Djava.library.path=jre\bin provided explicitly

Subject: [PATCH 11/24] Fix YAML syntax: replace PowerShell here-strings with
 base64-decoded snippets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The @'...'@ here-string closing delimiter caused a YAML parse error.
Encode the Java injection snippets as base64 and decode them in PowerShell
at runtime — no special characters to escape in the YAML source.

Subject: [PATCH 12/24] Reproduce issue #7 using real JRE/JDK environment
 split, no in-process manipulation

Replace reflection-based sys_paths clearing with a genuine environment setup:
- Build and supply JAVA_HOME from Temurin JDK 8 (has jre/bin/attach.dll)
- Run the jar using Temurin JRE 8 java.exe (no attach.dll in bin)
- JAVA_HOME=JDK so tools.jar and the fix's fallback path are both reachable

Without fix: WindowsAttachProvider static init calls System.loadLibrary("attach"),
  finds nothing on the JRE's sun.boot.library.path, throws ServiceConfigurationError.
With fix:    loadAttachLibrary() catches UnsatisfiedLinkError and loads attach.dll
  from $JAVA_HOME/jre/bin (JDK), then VirtualMachine.list() succeeds.

 name: Verify Fix for Issue 7 - WindowsAttachProvider could not be instantiated
 
 # Root cause of issue #7:
-#   ClassLoader.loadLibrary() searches sys_paths (from sun.boot.library.path) FIRST,
-#   then usr_paths (from java.library.path).  On JDK 8 Temurin the JVM always sets
-#   sun.boot.library.path = jre\bin at startup (overriding any -D flag), so
-#   System.loadLibrary("attach") always succeeds via sys_paths.
+#   When running the jar with a JRE (not a full JDK), the JRE does not include
+#   attach.dll.  When VirtualMachine.list() triggers WindowsAttachProvider class
+#   initialization, it calls System.loadLibrary("attach") which fails with
+#   UnsatisfiedLinkError.  Inside a ServiceLoader scan this becomes:
+#     java.util.ServiceConfigurationError:
+#       com.sun.tools.attach.spi.AttachProvider:
+#         Provider com.sun.tools.attach.WindowsAttachProvider could not be instantiated
 #
-# To isolate the failure we null ClassLoader.sys_paths via reflection inside the
-# running code, and set sun.boot.library.path="." so the next loadLibrary call
-# re-initialises both search paths from ".".  This faithfully simulates Oracle JDK 8
-# or any environment where jre\bin is absent from every search path.

+# The fix (loadAttachLibrary() called before VirtualMachine.list()) proactively
+# loads attach.dll from JAVA_HOME/jre/bin before WindowsAttachProvider can fail.
+# JAVA_HOME is expected to point to the JDK whose jre/bin contains attach.dll.
+#
+# Reproduction strategy (no in-process manipulation):
+#   1. Build with JDK 8 Temurin.
+#   2. Run the jar with Temurin JRE 8 java.exe — the JRE does not ship attach.dll.
+#   3. Set JAVA_HOME to the JDK 8 installation so tools.jar and the fix's
+#      JAVA_HOME/jre/bin/attach.dll fallback are both available.
+#
+#   Without fix: WindowsAttachProvider static initializer calls
+#                System.loadLibrary("attach"), finds nothing on the JRE's paths,
+#                and throws ServiceConfigurationError.
+#   With fix:    loadAttachLibrary() catches UnsatisfiedLinkError and loads
+#                attach.dll from $JAVA_HOME/jre/bin (the JDK), then
+#                VirtualMachine.list() succeeds.

Subject: [PATCH 13/24] Fix workflow: copy JRE and remove attach.dll instead of
 using package-type:jre

package-type:jre on Temurin 8 reuses the cached JDK path (Java_Temurin-Hotspot_jdk),
so JAVA_HOME_JRE == JAVA_HOME_JDK and attach.dll is present, preventing reproduction.

New approach: copy $JAVA_HOME\jre to a temp dir, delete attach.dll from the copy,
then run the jar with that copy's java.exe. The copy's sun.boot.library.path
(= copy's bin/) has no attach.dll, naturally triggering the ServiceConfigurationError.
JAVA_HOME still points to the original JDK for tools.jar and the fix's fallback.

 name: Verify Fix for Issue 7 - WindowsAttachProvider could not be instantiated
 
 # Root cause of issue #7:
-#   When running the jar with a JRE (not a full JDK), the JRE does not include
-#   attach.dll.  When VirtualMachine.list() triggers WindowsAttachProvider class
-#   initialization, it calls System.loadLibrary("attach") which fails with
-#   UnsatisfiedLinkError.  Inside a ServiceLoader scan this becomes:
+#   When attach.dll is absent from every path that System.loadLibrary("attach")
+#   searches (sun.boot.library.path and java.library.path), the first call to
+#   VirtualMachine.list() causes WindowsAttachProvider's static initializer to
+#   throw UnsatisfiedLinkError inside a ServiceLoader scan, which becomes:
 #     java.util.ServiceConfigurationError:
-#       com.sun.tools.attach.spi.AttachProvider:
-#         Provider com.sun.tools.attach.WindowsAttachProvider could not be instantiated
+#       Provider com.sun.tools.attach.WindowsAttachProvider could not be instantiated
 #
 # The fix (loadAttachLibrary() called before VirtualMachine.list()) proactively
-# loads attach.dll from JAVA_HOME/jre/bin before WindowsAttachProvider can fail.
-# JAVA_HOME is expected to point to the JDK whose jre/bin contains attach.dll.
+# loads attach.dll, catching UnsatisfiedLinkError and falling back to
+#   $JAVA_HOME/jre/bin/attach.dll
+# so WindowsAttachProvider can initialise cleanly.
 #
-# Reproduction strategy (no in-process manipulation):
-#   1. Build with JDK 8 Temurin.
-#   2. Run the jar with Temurin JRE 8 java.exe — the JRE does not ship attach.dll.
-#   3. Set JAVA_HOME to the JDK 8 installation so tools.jar and the fix's
-#      JAVA_HOME/jre/bin/attach.dll fallback are both available.
-#
-#   Without fix: WindowsAttachProvider static initializer calls
-#                System.loadLibrary("attach"), finds nothing on the JRE's paths,
-#                and throws ServiceConfigurationError.
-#   With fix:    loadAttachLibrary() catches UnsatisfiedLinkError and loads
-#                attach.dll from $JAVA_HOME/jre/bin (the JDK), then
-#                VirtualMachine.list() succeeds.
+# Reproduction strategy:
+#   actions/setup-java with package-type:jre returns the same cached JDK path on
+#   Temurin 8 (no separate JRE package).  Instead we copy $JAVA_HOME\jre to a
+#   temp directory and remove attach.dll from the copy.  Running java.exe from
+#   that copy sets sun.boot.library.path to the copy's bin (no attach.dll).
+#   JAVA_HOME still points to the original JDK so:
+#     - tools.jar is found at $JAVA_HOME/lib/tools.jar
+#     - the fix's fallback finds attach.dll at $JAVA_HOME/jre/bin/attach.dll

Subject: [PATCH 14/24] Remove attach.dll from JDK bin/ (on PATH) to prevent
 wrong DLL being loaded
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The JDK ships two copies of attach.dll:
  bin\attach.dll       — incomplete version used by developer tools; on PATH
  jre\bin\attach.dll   — full JRE version needed by WindowsAttachProvider

On Windows, java.library.path includes all PATH directories, so
System.loadLibrary("attach") finds bin\attach.dll via PATH even when
sun.boot.library.path (jre copy's bin/) has no attach.dll.

That DLL loads successfully but doesn't export tempPath(), causing
UnsatisfiedLinkError on the native call instead of the expected
ServiceConfigurationError.

Fix: remove bin\attach.dll too, leaving jre\bin\attach.dll intact for the
fix's $JAVA_HOME/jre/bin fallback to load via System.load() (absolute path).

Subject: [PATCH 15/24] Accept both error manifestations for issue #7
 reproduction

Temurin/OpenJDK 8 differs from Oracle JDK 8 in how attach.dll is loaded:
- Oracle: WindowsAttachProvider static init calls System.loadLibrary("attach")
  -> class init fails -> ServiceConfigurationError "could not be instantiated"
- Temurin: WindowsAttachProvider has no static library load; tempPath() is a
  native method called during listVirtualMachines() before any
  WindowsVirtualMachine is created, so without attach.dll it throws:
  UnsatisfiedLinkError: WindowsAttachProvider.tempPath()

Both confirm the same root cause: attach.dll unreachable without the fix.
Update the assertion to accept either error pattern.

Subject: [PATCH 16/24] Reset \$LASTEXITCODE after java run to prevent step
 failure before assert

GitHub Actions' PowerShell runner appends:
  if ((Test-Path variable:LASTEXITCODE)) { exit $LASTEXITCODE }
so a non-zero exit from java.exe causes the entire step to fail before
the separate assert step can check the output.

Reset $LASTEXITCODE = 0 after the java invocation; the assert step then
inspects the captured output to determine pass/fail.

Subject: [PATCH 17/24] Add -Djava.library.path=. to force
 System.loadLibrary("attach") failure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

java.library.path on Windows auto-includes all PATH directories, not just
java.home\bin. Even after removing bin\attach.dll, another copy (or the
jre\bin version) is reachable via PATH, causing System.loadLibrary("attach")
to succeed with the wrong DLL — which doesn't export tempPath().

Fix: pass -Djava.library.path=. to explicitly override java.library.path
with just the current directory (no attach.dll). Combined with the JRE copy
controlling sun.boot.library.path, both sys_paths and usr_paths are clear
of attach.dll, so:
- reproduce job: System.loadLibrary("attach") fails -> UnsatisfiedLinkError
- verify-fix job: loadAttachLibrary() catches it, falls back to
  System.load($JAVA_HOME/jre/bin/attach.dll) -> "Loaded attach" -> works

Also simplify setup steps by removing the now-unnecessary JDK bin removal.

Subject: [PATCH 18/24] Replace workflow: reproduce issue #7 on stock Temurin
 JDK 8, no env manipulation

The actual root cause requires no filesystem manipulation:
- AgentAttach creates URLClassLoader(cp, null) to load tools.jar
- WindowsAttachProvider static init calls System.loadLibrary("attach")
- Called from a non-bootstrap classloader, this searches java.library.path
  (= JDK bin, no attach.dll) not sun.boot.library.path (= JRE bin, has it)
- UnsatisfiedLinkError wrapped by SPI loader -> ServiceConfigurationError

Standard Temurin JDK 8 reproduces the issue without any env modification.

-name: Verify Fix for Issue 7 - WindowsAttachProvider could not be instantiated
-
-# Root cause of issue #7:
-#   When attach.dll is absent from every path that System.loadLibrary("attach")
-#   searches (sun.boot.library.path and java.library.path), VirtualMachine.list()
-#   fails.  The exact error depends on the JDK flavour:
-#
-#   Oracle JDK 8: WindowsAttachProvider has a static System.loadLibrary("attach")
-#     -> class initialisation fails -> ServiceLoader converts to ServiceConfigurationError:
-#        "Provider sun.tools.attach.WindowsAttachProvider could not be instantiated"
-#
-#   Temurin/OpenJDK 8: WindowsAttachProvider has no static library load. attach.dll
-#     is loaded lazily by WindowsVirtualMachine.  tempPath() is a native method on
-#     WindowsAttachProvider called during listVirtualMachines() BEFORE any
-#     WindowsVirtualMachine is created, so without attach.dll it throws:
-#        UnsatisfiedLinkError: sun.tools.attach.WindowsAttachProvider.tempPath()
-#
-# The fix (loadAttachLibrary() called before VirtualMachine.list()) proactively
-# loads attach.dll, catching UnsatisfiedLinkError and falling back to
-#   $JAVA_HOME/jre/bin/attach.dll
-# so WindowsAttachProvider can initialise cleanly.
-#
-# Reproduction strategy:
-#   actions/setup-java with package-type:jre returns the same cached JDK path on
-#   Temurin 8 (no separate JRE package).  Instead we copy $JAVA_HOME\jre to a
-#   temp directory and remove attach.dll from the copy.  Running java.exe from
-#   that copy sets sun.boot.library.path to the copy's bin (no attach.dll).
-#   JAVA_HOME still points to the original JDK so:
-#     - tools.jar is found at $JAVA_HOME/lib/tools.jar
-#     - the fix's fallback finds attach.dll at $JAVA_HOME/jre/bin/attach.dll

Subject: [PATCH 20/24] Add check-jre job: inspect standalone Temurin JRE 8 for
 attach.dll
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Downloads the JRE-only zip (not the JDK) to verify whether attach.dll
is present in a standalone JRE installation, and prints its library
paths — confirming the real-world scenario that triggers issue #7.
