Lars Herschke reopened TOMEE-2044:
----------------------------------
As far as I’m concerned, the problem still hasn’t been resolved.
??The ServerService that is saved in the variable service ist EjbServer.
EjbServer isn't instance of Unwrappable, so getQueue always return null.??
This problem still persists.
> threadPool-queue (in ServicePool) from ejbd-Service is never processed

> Project: TomEE
> Issue Type: Bug
> Components: TomEE Core Server
> Affects Versions: 1.7.4, 1.7.5, 1.7.6, 7.0.9, 7.0.10, 7.1.5, 9.0.0.RC1,
> 8.0.13, 8.0.14, 8.0.15, 10.0.0-M1, 9.0.0, 9.1.0

> Reporter: Lars Herschke
> Priority: Major
> Fix For: 7.0.4

>
> If you have many requests to your ejbd-service the queue from the threadPool
> in ServicePool.java is filled. This queue is never processed depending on
> your server config. If you have only ejbd-service enabled and the services
> admin, ejbds and httpejbd are disabled all is fine. If you have two or more
> of these services enabled the issue could occur. The reason is the following.
> KeepAliveServer.java has the following line to get the queue.
> final ServicePool incoming =
> SystemInstance.get().getComponent(ServicePool.class);
> SystemInstance.java hold components in a HahMap with the class type as key.
> On server-startup the above named services are initalized in
> ServiceManager.manage(...). This method instances new ServicePool for this
> services. Each ServicePool-instance calls in his constructor
> SystemInstance.get().setComponent(ServicePool.class, this);.
> Every other call of setComponent replace the old entry in the components
> HashMap. So KeepAliveServer gets always the queue of the last initalized
> service.
> Workaround:
> Use only one of the four above named services
> or
> set threadsCore for your services at least as high, that the queue is never
> used.
