java.lang.NullPointerException: name can't be null (similar to JCR-1272 issue)

Hi all,
I am using jackrabbit 1.4 as my content repository and the underlying database is derby. I am using jackrabbit-jca-1.4.rar connector to connect to respository from my web-app.
I am trying to store a file as one of the property of a node and then retrieving it. The problem is the property is being created but I am getting an exception while retrieving the property. Strangely when I restart my appserver where the jackrabbit-jca is deployed, I will be able to get the property without any exception being thrown. It may not be completely reproducible but definitely in my case it is failing most of the time.
I think this is similar to the bug : http://www.mail-archive.com/[EMAIL PROTECTED]/msg09384.html 

Any ideas why this is failing??

Regards,
Prakash
