While I don't have the answers, it would be helpful if you could
provide more details:
1. What version of commons-collections do you have (I checked 3.1 and
the line numbers do not match with the stack below)
2. Does it happen as a result of a certain sequence of events, or
does it happen randomly under heavy load?

Hi,
I'm not sure where to post it, but because I get this error by
cayenne I try it first here. A few days ago I reported a NPE within
the class apache.commons.map.LRUMap wich is used by the class
"DataRowStore". After synchronizing all access to the corresponding
field the NPE went away but now I have another exception:

Please check that your keys are immutable, and that you have used
synchronization properly. If so, then please report this to commons-
[EMAIL PROTECTED] as a bug.
