[Resteasy-users] Resteasy Client does not properly handle Server exception, rendering Client inoperable

[Anthony W. <an...@wh...>]

I discovered a particularly nasty problem using the Resteasy Client Framework and have documented it in the issue tracker:  https://issues.jboss.org/browse/RESTEASY-963

In a nutshell, if a Client Proxy instance makes a call to the service and the service throws an exception, the Client is now rendered inoperable because the underlying connection is not adequately reset.

A sample project is included with the issue that demonstrates the problem.  Note that there is a scenario (when a connection pool no longer has a valid connection available) where the call becomes FROZEN!

If I had to guess on the solution, I would say that the invoke method of ClientInvoker needs to catch the exception and release the underlying connection in the event of an exception.

https://github.com/resteasy/Resteasy/blob/master/jaxrs/resteasy-client/src/main/java/org/jboss/resteasy/client/jaxrs/internal/proxy/ClientInvoker.java#L104

I think this is similar to the issue raised by John D. Ament on the 15th.  (Resteasy should automatically clean up 
the connection, but this can not be limited to a GC event because we have no control over GC events.)

I look forward to seeing this fixed as this is a serious stability risk.  Thank you,

Anthony
