Subject [jira] [Created] (MYFACES-3735) NullPointerException in CompositeMetadataTargetImpl.<init>
Date Tue, 11 Jun 2013 14:39:20 GMT
Ulf Liller created MYFACES-3735:
-----------------------------------

             Summary: NullPointerException in CompositeMetadataTargetImpl.<init>
                 Key: MYFACES-3735
                 URL: https://issues.apache.org/jira/browse/MYFACES-3735
             Project: MyFaces Core
          Issue Type: Bug
            Reporter: Ulf Liller


In our application (MyFaces 2.1.10, RichFaces 4.2.2), the following exception is sometimes
(rarely) thrown when logging in. If that happens, it completely breaks the app, all subsequent
login attempts fail with the same exception.

I'm sorry that I can not give much info, we saw it happening during automated UI tests but
have not been able to reproduce it in a way that we can debug it.
