[jira] Issue Comment Edited: (CXF-1945) NullPointerException in
W3CDOMStreamReader
[ https://issues.apache.org/jira/browse/CXF-1945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12656370#action_12656370 ]

---------------------------------------------------------------
The problem only occurs on our production system, sometimes several times per day, sometimes after a couple of days.
We could go to 2.1.3 but I would rather not use a snapshot version. I checked the release notes but didn't see issues which might be related to this problem. But I see, that there have been quiet a few changes in the staxutils package, so 2.1.3 seems like a good idea.
I still suggest replacing
throw new IllegalStateException("Found type: " + content.getClass().getName());
by
throw new IllegalStateException();
as in revision 651669 or add a null pointer check.
But that won't solve our problem because then we will have an IllegalStateException without knowing why.
