jBPM 5.3 - TaskClient error

[jena74]

Hello,

I use the TaskClient Java API to connect to the HornetQ human task service started on my laptop.

But, each time, at the exit time of my Java code, I have a strange exception:

Exception in thread "Thread-1" java.lang.RuntimeException: Client Exception with class class org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1 using port 6666

    at org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1.run(HornetQTaskClientConnector.java:127)

    at java.lang.Thread.run(Thread.java:662)

Caused by: HornetQException[errorCode=102 message=Consumer is closed]

    at org.hornetq.core.client.impl.ClientConsumerImpl.checkClosed(ClientConsumerImpl.java:911)

    at org.hornetq.core.client.impl.ClientConsumerImpl.receive(ClientConsumerImpl.java:184)

    at org.hornetq.core.client.impl.ClientConsumerImpl.receive(ClientConsumerImpl.java:401)

    at org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1.run(HornetQTaskClientConnector.java:118)

    ... 1 more

I can not explain what happen, but if I run my test several times, at the end I am no more able to connect to my human task server.

I join the code of my client in attachment.

Does-it mean something for you please?

Thank you.

This is caused by shutdown of an active thread that is used to receive messages from the human task server and it is not properly disposed on client disconnect. I think you can use this without any risk as thread it closed just not really in the best manner.

Hi,

Thank you for your answer.

Indeed I have not seen any side effect regarding this exception but I just wanted to try to remove it.

Thank you.
