it happens only on JDK>=15 (we are trying an upgrade), works correctly with JDK11

I think it has something to do with implicit mapping, it doesn't block when I disable it

Hi @malteo -

Can you provide more information? When I thread was blocked, there might be another thread which was running and holding the lock. Thanks.

And maybe some source. code is helpful.

it doesn't happen with JDK 17 ¯\(ツ)/¯

I see the same issue on Apple M1, using JDK 17. If I switch to Zulu Java 11 JDK this issue doesn't happen.
