Nelson RIvera commented on UIMA-5477:
-------------------------------------
This behavior is random, not occurs always. In the most of the simple programs
and simple test case tested, after restart the UIMA-AS Broker without restart
service uima-as, the instruccion to uima-as client
"BaseUIMAAsynchronousEngine_impl.connectionOpen()" return "false" and correctly
i initialize the client again.
The incorrect behavior is most frequently with many uima-as client instances.
Is the case of my general application in which i have many service uima-as, and
for each one creates one instace of uima-as client
(BaseUIMAAsynchronousEngine_impl) and keep it alive to process all requests of
the service uima-as.
Is in this scenario with many instancies of uima-as client
(BaseUIMAAsynchronousEngine_impl) in the same program (a monolithic application
web in tomcat) where after restart the UIMA-AS Broker without restart any
service uima-as, many uima-as client returns "true" to the instruccion
"BaseUIMAAsynchronousEngine_impl.connectionOpen()" but them throw
"javax.jms.IllegalStateException: The Session is closed"
when proces the request.
> javax.jms.IllegalStateException: The Session is closed after establish
> connections between uima-as client and ActiveMQ

> URL: https://issues.apache.org/jira/browse/UIMA-5477
> Project: UIMA
> Issue Type: Access
> Components: Async Scaleout
> Affects Versions: 2.9.0AS
> Environment: ubuntu xenial, openjdk-8-jdk
> Reporter: Nelson RIvera
>
> In my program main, i initialize a uimas-as client only once and I use
> this client to consume all requests to a displayed service uima-as.
> Before process a request i ask to uima-as client with:
> BaseUIMAAsynchronousEngine_impl.connectionOpen()
> and if the result es "false", i stop the uima-as client and initialize it
> again.
> With some steps, still undefined, but basically when restart the UIMA-AS
> Broker
> without restart service uima-as.
> The instruccion to uima-as client
> BaseUIMAAsynchronousEngine_impl.connectionOpen() return "true", but
> them i get a "javax.jms.IllegalStateException: The Session is closed"
> when proces the request.
> One peculiarity is that, is a primitive annotator implented in c++,
> but is deployed with de deployAsyncService.sh de uima-as directly.
