----------------------------------------------------------------
In the current Revision (797700) the error behaviour has slightly changed. Now
a NullPointerException is thrown when ExtensionContext::complete() is called.
(at org.apache.ode.c4b.extensionBundle.ReceiveContextEventAdapter is my
AsyncExtension Class)
The Stacktrace is
java.lang.NullPointerException (null)

> Process blocks although Async Extension Operation is marked completed or

>
> Key: ODE-606
> URL: https://issues.apache.org/jira/browse/ODE-606
> Project: ODE
> Issue Type: Bug
> Components: BPEL Runtime
> Affects Versions: 2.0
> Environment: Tomcat5.5 Ode Trunk Rev 766476 Debian Linux 1,5G RAM,
> integrated DB
> Reporter: Christian Fonden
> Assignee: Tammo van Lessen
>
> When a new extension Activity extending AbstractAsynchExtensionOperation is
> developed and deployed, a bad scheduler issue occurs:
> - the run method does neither complete with errors nor it completes
> successfully (intended!)
> - a java timer waits 10 seconds and the calls context.completeWithFault.
> - then the activity gets marked as faulted, but the process runs until it is
> stopped by the 30 second axis2 call timeout, returning the axis2 stack trace
> to the invoking client.
> It seems like the situation that the activity marks itsself as faulted by
> calling the context.completeWithFault() method in the ExtensionContext class
> is somehow *not* being propagated to the navigator and the whole BPEL Process
> is blocked by the faulted Activity. Also no compensation is called.
> Again to make it clear: the time integrated in the extension fires after 10
> seconds, but the process completes on Axis2 Timeout after 30 seconds.
> The missing code can be easily reproduced by
> - create a synchronous bpel process, containing just the async extension
> activity
> - the extension activity starts a timer in its run() method
> - the timer calls completeWtih fault after a short time (e.g. immediately)
> - the process is still blocked.
