ARTEMIS-4751 upgrade to Apache parent 32

Due to https://github.com/apache/maven-apache-parent/pull/188 the
property `maven.compiler.release` is now being set which precludes
exporting and using any internal Java classes. Therefore this commit
removed references to `--add-exports` from the build, switches to
reflection, and adds `--add-opens` to the runtime JVM parameters.
