> --------------------------------------------------------------
>
> Key: QPID-6684
> URL: https://issues.apache.org/jira/browse/QPID-6684
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Fix For: qpid-java-6.0
>
>
> A defect in the following part of the ACO#doAttainState means that an asynchronous exception occurring in a state change method is lost and not propagated back via the future returned to the caller.
> {code:java}
> final SettableFuture<Void> returnVal = SettableFuture.create();
> final ChildCounter counter = new ChildCounter(new Runnable()
> {
> @Override
> public void run()
> {
> try
> {
> ### If future returned by attainState contains an exception, it is lost. returnVal future completes normally regardless..
> attainState().addListener(new Runnable()
> {
> @Override
> public void run()
> {
> returnVal.set(null);
> }
> }, getTaskExecutor().getExecutor());
> }
> catch(RuntimeException e)
> {
> try
> {
> exceptionHandler.handleException(e, AbstractConfiguredObject.this);
> returnVal.set(null);
> }
> catch(Throwable t)
> {
> returnVal.setException(t);
> }
> }
> }
> });
> {code}
