Description

Hello.

I'm trying to use OpenJPA in my project. I use Liferay based on Toncat as front-end.

I use OpenJPA 1.0.0

Today I have got strange exception -

10:35:55,785 ERROR ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:787) at java.util.HashMap$KeyIterator.next(HashMap.java:823) at org.apache.openjpa.kernel.BrokerImpl$ManagedCache.dirtyCheck(BrokerImpl.java:4612)

It happens only, when I deploy application on portal, and only when service is first-time accessed.

All tests work fine.

Exception throws in get method
Transactions are managed by Spring and i use Spring agent.
