Hi @mfussenegger would you have any suggestions for #380 (comment)? I could not find out where this option was coming from.

Hi @mfussenegger would you have any suggestions for #380 (comment)? I could not find out where this option was coming from.

Earlier versions of CrateDB used UseConcMarkSweepGC as garbage collector. That was removed in later JDK versions (https://openjdk.org/jeps/363) - hence the error.
One option could be to try and setting CRATE_JAVA_OPTS="-XX:+IgnoreUnrecognizedVMOptions" for the older CrateDB versions.

If that doesn't work we may have to extend the logic in https://codeberg.org/mfussenegger/cr/src/commit/master/cr8/java_magic.py so that it searches and uses an older JDK for those versions.

Or maybe we find a way to have checkstyle run using the toolchain, so it doesn't depend on having JDK17 available for the build.
