Remove -XX:MaxPermSize from poms to allow builds with Java >= 17

-XX:MaxPermSize is deprecated since Java 8, obsolete since Java 16 and unsupported since Java 17. See:

https://docs.oracle.com/en/java/javase/16/docs/specs/man/java.html#obsolete-java-options

This fixes the docker build with Java 19.
