+  # Canary job: run the test suite against an upcoming, not-yet-released JDK.
+  # setup-java has no first-class EA distribution, so we download the OpenJDK
+  # EA archive ourselves and install it via `distribution: 'jdkfile'` (which
+  # extracts/caches it and sets JAVA_HOME). We capture that JAVA_HOME as the
+  # *test target*, then set up a stable LTS JDK afterwards so Gradle itself
+  # runs on a GA build. `fail-fast: false` keeps EA breakage from failing the
+  # rest of the matrix. NOTE: the EA build number bumps ~weekly, so the URL
+  # below goes stale — refresh it (and java-version) from https://jdk.java.net/27/.
