An NPE is thrown to Error Log view when trying to specifying the value of joinColumns for JoinTable annotation. At that moment, the annotation is like @JoinTable(joinColumns = ).

Reproducible: Always

Steps to Reproduce:
1. Apply @JoinTable annotation to an attribute of a Java entity
2. Specify the joinColumns element of JoinTable annotation
3. Trying to specifying the value of the joinColumns element

Not able to reproduce this in head, but I can reproduce in maintenance.  My guess is this has been fixed in head.  Nan, please try to verify with the following build:

I believe Karen fixed this NPE in just the last couple of months. Probably with the check-in of AnnotationContainerTools 1.8 on 10 Sep 2010. There is a similar problem in bug 323005 that was fixed in both maintenance and HEAD in August.
Comment 6 Neil Hauge CLA 2010-11-19 09:19:49 EST 
Sounds good.  Marking as fixed in M2.  Please reopen if reproduced in Head.
