Answer 1

The issue had to do with netty native libraries that were not compatible with JDK 21. Netty 4.1.99.Final fixes this.

Netty 4.1.99.Final released: We are happy to announce the release of netty 4.1.99.Final. This release fixes a bug which could lead to SIGSERV while running on JDK21+. As JDK21 was recently released and is considered an LTS release we did decided to do this emergency release. Because of the nature of this bug (crashing the JVM) you should upgrade ASAP.
