Hello,
My application uses Tomcat6,derby,spring and OpenJPA 1.20.
My case is stopping derby database and restarting it. And I found even
if I catch the database connection broken exception and create an new
EntityManager successfully after derby restarts, the following
exception stack will be printed :
<2009-06-05 15:22:21,140> <ERROR> <com.***.ds.Persister.persist:203>
<Persistence-thread-1> <The context has been closed. The stack trace
at which the context was closed is available if Runtime=TRACE logging
is

<openjpa-1.2.1-r752877:753278 fatal user error>
org.apache.openjpa.persistence.InvalidStateException: The context has

And I ensure the new EntityManager connect derby successfully by
netstat -an|grep 1527.
I closed all cache of OpenJPA but same error still happen.
