Description Paul Fullbright CLA 2011-10-11 11:35:01 EDT 
Create *any* class in a JPA or JAXB project.  Change (via text editor) to enum.  Get the following NPE:

java.lang.NullPointerException
	at org.eclipse.jpt.common.core.internal.resource.java.source.SourceAnnotatedElement.syncAnnotations(SourceAnnotatedElement.java:252)

The NPE will continue happening for the life of the class/workbench session.
Comment 2 Karen Butzke CLA 2011-10-11 14:48:07 EDT 
This is only an issue in JPA in the 3.1 stream. This problem exists in JAXB in 3.0 and 3.1 where we had separate java resource models for JPA and JAXB.

Paul, did you actually test this in 2.3.4?
Comment 3 Paul Fullbright CLA 2011-10-11 14:51:02 EDT 
No, 2.3.4 was the automatic entry, which is weird.  It exists in current code.

Verified in Build M-3.3.2-20111107105838 

Verified you can change class to enum in java class editor without error.  See the link to view test steps for verification. http://wiki.eclipse.org/Dali_3.0.2
