Vikram Bhatia commented on OPENJPA-230:
---------------------------------------
Well I have though about it, but it fails the following scenario.
1. Four Threads running and eight Packets in queue. The four threads are busy
sending packets.
3. In case, _keepRunning is set to false, four packets will still be left to
synchronize as threads exit from while loop.
> 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.
