Rethrown checked exception should not be wrapped within ObserverException
-------------------------------------------------------------------------
Key: SOLDER-290
URL: https://issues.jboss.org/browse/SOLDER-290
Project: Seam Solder
Issue Type: Bug
Components: Exception Handling
Affects Versions: 3.1.0.Beta3
Reporter: Jozef Hartinger
Fix For: 3.1.0.CR1
The spec says:
{quote}Otherwise, the exception aborts processing of the event. No other
observer methods of that event will be called. The
BeanManager.fireEvent() or Event.fire() method rethrows the exception. If the
exception is a checked exception,
it is wrapped and rethrown as an (unchecked) ObserverException.{quote}
Therefore, everytime an exception handler marks the exception to be rethrown,
ExceptionHandlerDispatch.executeHandlers() rethrows the exception. If the
exception is checked, the CDI implementation must wrap the exception within
ObserverException. As a result, the exception is rethrown within the
ObserverException wrapper.
Everytime we notify the dispatcher using via the ExceptionToCatch event
bm.fireEvent(new ExceptionToCatch(e)), we should check if the call raises an
exception and if it does raises ObserverException, we should unwrap it.
This should be also documented for other integrators to do the same thing.
