I tried to work with eclipselink 2.7.0 with gemini. However, I get the following exceptions:

ERROR: Bundle org.eclipse.gemini.jpa [58] EventDispatcher: Error during dispatch. (java.lang.NullPointerException)
java.lang.NullPointerException

The exceptions only appear when I use eclipselink 2.7.0 and don't appear when I use eclipselink 2.6.3.

EclipseLink 2.7.0 hasn't even been released yet, has it?

P.S. Please specify which Gemini subproject you are referring to in the title when you post a question as this forum is for all Gemini projects. I have modified the subject title accordingly.

Yes, it hasn't but I think it could work. Can you explain what I do wrong while posting questions? I select eclipse forum -> gemini. Is this not enough?

Ok, you get to be the one to find out what the problem is, then. Smile
If it is an EclipseLink problem then you can report it to them on the EclipseLink forum, otherwise report your findings back on this thread.

There are 6 different Gemini subprojects. When you create a new post and are asking about Gemini JPA, include Gemini JPA (not just Gemini) in the subject line of the post so it is clear which Gemini subproject you are asking about. For example, you started this thread with "Does Gemini work with EclipseLink 2.7.0?" and I changed the title in my reply to "Does Gemini JPA work with EclipseLink 2.7.0?"
