Why is Eclipse Juno 4.2 running "JPA Java Change Event Handler" processes?
===

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 some Eclipse metadata in them.

When moving to 4.2 I converted a project to use "Project Facets". The only Facet enabled is "Java".

However, I regularly get "JPA Java Change Event Handler (Waiting)" appearing in my progress view. I do have JPA annotated classes within the project, but I do not have the JPA facet enabled.

So...why am I getting these tasks being run by Eclipse?
