dev-java/gradle doesn't compile with Java 21.

[MarkusTieger]

The error:

This build requires JDK 11. It's currently /usr/lib64/openjdk-21. You can ignore this check by passing '-Dorg.gradle.ignoreBuildJavaVersionCheck=true'.

Current workarround:

• Set the default java to 11

And ofc:

!!! When you file a bug report, please include the following information:
GENTOO_VM=  CLASSPATH="" JAVA_HOME=""
JAVACFLAGS="" COMPILER=""

And after that a sandbox access violation: sandbox.log
