Why is Eclipse Juno 4.2 running “JPA Java Change Event Handler” processes?

Question

I have just upgraded to Eclipse Juno 4.2. I have a completely clean new workspace, but have imported projects that have previously been used in Eclipse 3.7 and therefore have so

Answer 1

I had the same issue I had the same issue in eclipse 4.5.2 (mars 2). I've tried almost every answer from stackoverflow, tuned my eclipse settings (I thought maybe its a performance issue).

Problem stops after disabling JPA in Project Facets in every Project properties.

After this change Eclipse keeps yelling about JPA Event Handler but it doesn't take ages to finish save or clean, so it looks like its disabled (before changing this it took something about 10 minutes to finish, now its matter of seconds)

Hope that help someone to fix this problem.
