Proposed fix: [JDK upgrade] 'Unrecognized VM option 'X'' + 'Error: Could not create the Java Virtual Machine.' — expired -XX flags left in JAVA_OPTS/MAVEN_OPTS/GRADLE_OPTS/org.gradle.jvmargs/JAVA_TOOL
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Find where the flag comes from (echo $JAVA_OPTS $JAVA_TOOL_OPTIONS $MAVEN_OPTS $GRADLE_OPTS; .mvn/jvm.config; gradle.properties org.gradle.jvmargs; Dockerfile ENTRYPOINT) and remove/replace it; the JVM may print a 'Did you mean ...' suggestion. Use -XX:+IgnoreUnrecognizedVMOptions only as a temporary crutch.
Option: Remove expired flags from JVM option sources [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. grep -rn 'XX:' .mvn/jvm.config gradle.properties Dockerfile .github/workflows
2. env | grep -E 'JAVA_OPTS|JAVA_TOOL_OPTIONS|MAVEN_OPTS|GRADLE_OPTS'
3. Delete or replace the flag (e.g. MaxPermSize → MaxMetaspaceSize if a limit is really needed)
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
