Cannot build on Java 11

When trying to build a UIMA project with the PP 15 on Java 11, the java11 profile is activated and that adds a --illegal-access=permit flag to surefire which is not supported by the Java 8 toolchain that we use. That means, the build fails.

Also, if we build with a higher version like Java 17, the profile is not activated (not adding jaxb stuff) and everything still works - so it appears we may not need this profile.
