Keith Wall created QPID-6684:
--------------------------------
Summary: Asynchronous state change exceptions not passed back to
caller
Key: QPID-6684
URL: https://issues.apache.org/jira/browse/QPID-6684
Project: Qpid
Issue Type: Bug
Components: Java Broker
Reporter: Keith Wall
Assignee: Keith Wall
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}
