[jira] Created: (SM-1710) running servicemix-http unit tests stalls
intermittently
running servicemix-http unit tests stalls intermittently
--------------------------------------------------------
Key: SM-1710
URL: https://issues.apache.org/activemq/browse/SM-1710
Project: ServiceMix
Issue Type: Bug
Affects Versions: servicemix-http-2008.01
Reporter: Gert Vanthienen
Assignee: Gert Vanthienen
Fix For: servicemix-http-2008.02
If I run the unit tests a few times in a row, I'm bound to get the tests in a locked up state.
At first glance, it seems to lock up inside the provider endpoint (a.o. in ProviderEndpointTest), right after all the servicemix-soap interceptors have been executed, with all Jetty qt* threads either waiting or sleeping.

Gert Vanthienen updated SM-1710:
--------------------------------
Attachment: jetty-deadlock.txt
The stalls are being caused by a deadlock between ServiceMix and Jetty that both want to synchronize on the SelectSet and RetryContinuation

[jira] Reopened: (SMXCOMP-161) running servicemix-http unit tests

Guillaume Nodet reopened SMXCOMP-161:
-------------------------------------
The fix prevents any synchronization from the endpoint to occur as a new wrapper is created each time the continuation is retrieved.

Gert Vanthienen resolved SM-1710.
---------------------------------
Resolution: Fixed
Fixed in http://svn.eu.apache.org/viewvc?view=rev&revision=728661
A RetryContinuation is now wrapped in a ContinuationWrapper, so the endpoint can synchronize on the wrapper and jetty can continue to synchronize on the continuation itself without risking a deadlock. For a WaitingContinuation, we always synchronize on the Continuation object itself.
