Migrate corfudb-cloud to JDK 25

[chetangudisagar]

Changes Made

Gradle Wrapper (6 files)

• Upgraded Gradle from 8.10 to 9.1.0 across all subprojects
  (root, universe, tests, benchmarks, cloud/infrastructure,
  cloud/corfu/corfu-client-example).
  Gradle 9.1.0 is required for JDK 25 support (8.10 only supports up to Java 23).

Java Compilation (gradle/java.gradle)

• sourceCompatibility and targetCompatibility updated from VERSION_21
  to VERSION_25.
• Added --add-opens JVM flags for JDK 25's stricter module encapsulation:
  java.base/java.net, java.base/java.lang, java.base/java.util,
  java.base/java.lang.reflect, java.base/java.io,
  java.management/sun.management, jdk.attach/sun.tools.attach.
• Added testRuntimeOnly dependency on junit-platform-launcher:1.5.2
  (required by Gradle 9.x - JUnit Platform launcher must be explicitly
  on the test runtime classpath).

Groovy/Gradle 9.x API Compatibility (gradle/idea.gradle)

• groovy.util.XmlParser -> groovy.xml.XmlParser (moved in Groovy 4.x)
• QName import changed from groovy.xml.* to groovy.namespace.QName
• compileJava.destinationDir -> compileJava.destinationDirectory.asFile.get()
  (destinationDir removed in Gradle 9.x)

Gradle 9.x API Compatibility (gradle/universe.gradle)

• JavaExec.main -> JavaExec.mainClass.set() (main property removed in
  Gradle 9.x) for deployment and shutdown tasks.

Lombok Plugin Upgrade (4 files)

• io.freefair.lombok upgraded from 8.12.1 to 9.2.0 in:
  universe/universe-core/build.gradle.kts
  universe/universe-infrastructure/build.gradle.kts
  tests/build.gradle.kts
  benchmarks/build.gradle.kts
  (8.12.1 is incompatible with Gradle 9.x; 9.2.0 bundles
  Lombok 1.18.40+ which supports JDK 25)

Protobuf Plugin Upgrade (2 files)

• com.google.protobuf upgraded from 0.9.3 to 0.9.6 in:
  benchmarks/build.gradle.kts
  tests/build.gradle.kts
  (0.9.3 uses Configuration.fileCollection() which was removed in Gradle 9.x)

Palantir Docker Plugin Upgrade (3 files)

• com.palantir.docker upgraded from 0.36.0 to 0.37.0 in:
  tests/build.gradle.kts
  cloud/infrastructure/integration-tools/build.gradle.kts
  cloud/infrastructure/kibana/kibana-tools/build.gradle.kts
  (0.36.0 uses ImmutableAttributesFactory internal API removed in Gradle 9.x)
• Added pluginManagement block with Maven Central repository and
  resolutionStrategy in tests/settings.gradle.kts (0.37.0 is published
  to Maven Central but not the Gradle Plugin Portal).

Checkstyle Fix (FakeDns.java)

• Added missing blank line before class declaration
• Added braces to single-line if statement

GitHub Actions Workflows (4 files)

• pull_request_universe.yml: java-version 21 -> 25
• pull_request_benchmarks.yml: java-version 21 -> 25
• publish-universe-artifacts.yml: java-version 21 -> 25
• run_benchmarks.yml: java-version 21 -> 25

Dockerfiles (5 files)

• tests/Dockerfile: openjdk:21-bullseye -> eclipse-temurin:25-jdk-noble
• benchmarks/Dockerfile: openjdk:21-bullseye -> eclipse-temurin:25-jdk-noble
• cloud/corfu/corfu-client-example/Dockerfile: openjdk:21-bullseye -> eclipse-temurin:25-jdk-noble
• cloud/infrastructure/integration-tools/Dockerfile: openjdk:21-bullseye -> eclipse-temurin:25-jdk-noble
• cloud/infrastructure/kibana/kibana-tools/Dockerfile: openjdk:21-bullseye -> eclipse-temurin:25-jdk-noble

Note: Also migrated from deprecated openjdk Docker images to eclipse-temurin
(Adoptium), which is the recommended OpenJDK distribution.

Verified locally with JDK 25.0.2:

• ./gradlew check passes in universe/
• ./gradlew check passes in benchmarks/
• ./gradlew compileJava compileTestJava passes in tests/
  (tests/check has pre-existing checkstyle and Docker integration test
  failures unrelated to JDK migration)
