Daniel Persson commented on OPENJPA-2193:
-----------------------------------------
Hi Rick.
We are using tomcat and non-jta-data-source handled by tomcat.
Our tests are done from jMeter doing a lot of request to tomcat where each
request creates a new user and uses this new user for the operational part of
the query to the server.
During two of these we get the null pointer exception. Could be the tomcat
pooling that is the reason for failure perhaps.
Best regards
Daniel
