Andreas Veithen commented on WSCOMMONS-544:
-------------------------------------------
The issue can be reproduced using the transport testkit. See the test case
disabled in r947447:
http://svn.apache.org/viewvc/axis/axis2/java/transports/trunk/modules/mail/src/test/java/org/apache/axis2/transport/mail/MailTransportTest.java?rev=947447&r1=947446&r2=947447&view=diff
> Mail transport: synchronous invocation style doesn't work correctly

> Key: WSCOMMONS-544

> Project: WS-Commons
> Issue Type: Bug
> Components: Transport
> Reporter: Andreas Veithen
>
> The change in r698486 introduced support for the synchronous invocation style
> in the mail transport. This was implemented by using a callback pattern where
> the transport sender waits until the transport listener receives the response
> message and invokes the callback. This however doesn't work as expected. The
> reason is that after receiving the message, the mail transport listener will
> close the input stream for the message (and potentially release some other
> resources, such as closing the mail folder). On the server side, this works
> well because the listener invokes AxisEngine.receive, which only returns
> after the service has processed the message. However, on the client side, it
> will invoke the callback, which will not process the message, but only store
> it. By the time the client attempts to process the response, the underlying
> input stream is already closed. This leads to errors such as this one:
> java.lang.RuntimeException: [was class java.io.IOException] Stream closed
