Vikram Bhatia commented on OPENJPA-230:
---------------------------------------

I tried this too, but what will happen in case thread is already in wait() 
state, and there are no more packets. join() will keep on waiting forever and 
process will never exit.

> Handle guaranteed delivery of Data Cache events on normal JVM termination 
> using TCPRemoteCommitProvider

> When an application is commiting a transaction and then terminating, often 
> not all events regarding Data Cache are dispatched by the 
> TCPRemoteCommitProvider. It seems that the JVM on termination is not waiting 
> until TCPRemoteCommitProvider has dispatched all events regarding Data Cache. 
> In this way some cache synchronization is lost.
