@dpsoft Any thoughts? This kind of wizardry is usually your specialy 🧙‍♂️

[dpsoft]

Hi, you can try with --add-opens java.base/java.util.concurrent=ALL-UNNAMED as JVM param

[yarosman]

with adding --add-opens java.base/java.util.concurrent=ALL-UNNAMED to JavaOpts everything was work correct

Are there plans to get rid of this workaround / be future compatible?
