> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.3.1AS
>
>
> JmsEndpointConnection_impl does not synchronize access to JMS Session object
> to prevent multiple threads from accessing it. Per JMS spec. Section 4.4.6:
>
> "Sessions are designed for serial use by one thread at a time."
> There are four methods in the above class where access to the JMS Session is
> not synchronized:
> produceTextMessage()
> produceByteMessage()
> produceObjectMessage()
> isOpen()
