After registering GlassFish 4, there are several files created under ~userdir/config/org-netbeans-api-project-libraries/Libraries:
What are these used for? Are they needed? I even see that:
- the Comet one is empty
- none of them have Maven info - will they work with Maven?
If they are not used by any code, then they should not be created.
Will try to check them.
