> when setup txbridge under Tomcat8 out of JBoss, I am facing performance issue as below scenario;
> 1) running 3 tomcat instances
> 2) A call B via WS
> 3) B call C via WS
> 4) when 100 - 200 GET query from " http://localhost:8081/user?action=add " via Service A, all 3 tomcat got stuck for a while then raise exception with attached logs
> sth similar with quickstart example but no EJB and out of JBoss from https://github.com/jbosstm/quickstart/tree/master/XTS
> ==================================================
> WS-AT to JTA (Multi Hop)
> This example demonstrates a JTA client that invokes a remote EJB over Web services. The JTA transaction is distributed to the remote EJB using WS-AtomicTransaction. The service also acts as a client to a second service. Again using WS-AT to distribute the transaction over Web services.
> ==================================================
> {code}
>      servlet client - localhost:8081/user?action=add

> this may caused by race condition/socket timeout/exceed limits, will need to reproduce and research more;
> at the beginning I thought it was caused by DB resource locking failed but after I commented out all DB access, the problem still there
> put all my code to https://github.com/JonkeyGuan/txbridgeInTomcat8 for reproducing and reference
