-------------------------------------
Any update?
> Route deadlock in DefaultReactiveExecutor/Worker in transactional route which
> calls Camel Proxy bean
> ----------------------------------------------------------------------------------------------------
>
> Key: CAMEL-16927
> URL: https://issues.apache.org/jira/browse/CAMEL-16927
> Project: Camel
> Issue Type: Bug
> Components: camel-core-engine
> Affects Versions: 3.7.5, 3.7.2
> Reporter: Piotr Klimczak
> Priority: Major
> Fix For: 3.7.6
>
>
> My scenario:
> # Http client -> Transactional servlet consumer
> # Servlet route calls java bean
> # Java bean calls another route using Camel Proxy and direct-vm
> # CamelInvocationHandler calls direct-vm route and then hangs as route is
> never executed, waiting for worker
> At this point it is all deadlocked and it never ends.
> From what I can see the problem happens in DefaultReactiveExecutor.Worker.
> From debugging I can see there are two DefaultReactiveExecutor.Workers at the
> point of deadlock.
> At point 3, Worker number 2 executes SimpleTask which waits for it to finish-
> this task is to execute bean as per step 3.
> Bean execution then attempts to trigger another route using Camel Proxy and
> direct-vm and schedules it on Worker number 2.
> However immediately after scheduling on Worker number 2 the direct-vm
> processor, Worker 1 executes executeFromQueue (triggered by countdownLatch
> waiting for direct-vm call to finish) which then causes deadlock because task
> added to Worker number 2 is never executed.
> I have confirmed above in debugging, will try to come up with simple test
> case as our scenario is rather complex and involves multiple projects.
> Unfortunately for us this is blocker as our solution which was working
> perfectly fine with camel 2 is not working.
