All,
I am getting the following exception when trying to add anode. It goes from
being sporadic to consistent back to sporadic.
java.lang.NullPointerException

I researched this error a little bit, it seems like the exact same issue was
reported as a Jackrabbit bug [1], which was attributed to a version of the IBM
JDK. Apparently it is a bug with the IBM JDK [2]. Although the IBM bug says it
affects Websphere users, but it's a bug with their JDK and I am inclined to
think it would affect all users of that version of the IBM JDK.
We are running Jackrabbit 2.2.5 deployed in Weblogic running on AIX with IBM
JDK. I would appreciate if someone knows more details or could suggest a
workaround/resolution.
Thanks
Sumit
