Subject ConcurrentModificationException at org.apache.openjpa.kernel.BrokerImpl
Date Wed, 10 Oct 2007 11:43:57 GMT
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 -

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
