How do I combine @Asynchronous and Weld/CDI Events and @Observes(during=TransactionPhase.AFTER_COMPLETION) in Glassfish 3.1

问题

First of all let me state, that the following code example worked just fine in GF 3.0.1. The troubles started when we switched to GF 3.1.

I'm using a method

@Asynchronous
public void executeFlowStep(
    @Observes(during=TransactionPhase.AFTER_COMPLETION) 
    ExecuteFlowStepEvent executeFlowStepEvent) { 

Since the switch, whenever this should receive an ExecuteFlowStepEvent I get the following error message:

WELD-000401 Failure while notifying an observer of event [package].ExecuteFlowStepEvent

No further information or stacktrace is given. It works if I remove the @Asynchronous annotation and the AFTER_COMPLETION attribute, of course this breaks the program as I depend on the AFTER_COMPLETION timing.

I tried to ask for help on the Weld Forums, so far to no avail, although there seem to be other people with the same problem: http://seamframework.org/Community/WeldUsers

I at least would like to know: Is this a bug, or is this wanted. Does this imply that Weld does NOT work with Asynchronous methods/AFTER_COMPLETION attributes? Why did this work in GF 3.0.1? Has anyone managed to make this work on GF 3.1?

回答1:

According to the link you posted as a comment to your own question, this is a bug that was fixed in Wield 1.1.2 and GlassFish 3.1.2 (build 14+).

disclamer: I posted this answer to an age old question to help SO (StackOverflow) get rid of unanswered questions.
