Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses compatibility issues when running Nexmark tests on newer Java versions. By configuring specific JVM 'add-opens' flags for the Spark runner, the changes ensure that the test suite can properly access internal Java modules required for execution on JDK 17+ environments.

Highlights

• JVM Compatibility: Added necessary JVM arguments to support running Nexmark tests on Java 17 and higher.
• Build Configuration: Introduced a helper function in the build script to dynamically inject '--add-opens' flags for Spark-based test executions.

Code Review

This pull request introduces a helper method sparkJvmArgs() in sdks/java/testing/nexmark/build.gradle to conditionally append JVM --add-opens arguments when running with Java 17 or higher. The reviewer suggested a more robust way to parse and compare the Java version using Gradle's JavaVersion.toVersion() to prevent potential NumberFormatException errors when parsing version strings.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Parsing testJavaVersion directly as an integer using as int can throw a NumberFormatException if the version is specified in a format like "1.8" or "11.0".

Using Gradle's built-in JavaVersion.toVersion() is much more robust as it correctly handles various Java version string formats (e.g., "1.8", "8", "17") and allows for safe comparison using JavaVersion enum constants.

  def testJavaVer = project.findProperty('testJavaVersion') ? JavaVersion.toVersion(project.property('testJavaVersion')) : JavaVersion.current()
  if (testJavaVer >= JavaVersion.VERSION_17) {
