I have tried with the default for JAVA_HOME in the extension settings and also with /usr/lib/jvm/java-21-openjdk-amd64.

Hi there @janes

Thanks a lot for the report! Indeed, there is a bug in the current version that prevents Open in IDE feature to work properly. This has now been fixed and will be part of the version 4.30.

Apologies for the inconvenience and all the best,
Sophio
