Replace "ParameterizedTypeImpl" Java class (not present in OpenJDK 11)

Part of #6197

The problematic class is: mage.watchers.Watcher (uses the deleted class sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl)

The problematic commit is https://github.com/magefree/mage/commit/1a8723697ec547f4c9659dc61a0dc876f05dcf90

According to https://winterbe.com/posts/2018/08/29/migrate-maven-projects-to-java-11-jigsaw/, it could be that PrameterizedTypeImpl could be well replaced by its interface, ParameterizedType. Finally, according to the official Migration Guide, the replacement for this class is javax.lang.model.type.DeclaredType.

@ingmargoudt Whereas I am not very experienced in this, the class switch does not seem too difficult. I could try implementing the switch myself, if I can get some mentoring.
