Hello -

In regard to your bug (quoted below), I'll need more information regarding
the environment and a test case would be very helpful. Does this error
happen all the time? Frequently? Rarely? etc...

I can say that I exercise this code often without issue. The most likely
cause of this error is generally that it's being done in a threaded
environment without adequate thread safety. Try wrapping the maps in
TCollections.synchronizedMap(...) and see if that helps.

For now the bug will be put into PENDING state and will automatically close
if no further comments are made within 10 days. Please reply to this email
or comment on the bug with additional details.

Thanks!
Rob
