Attachment: uimaj-as-jms-UIMA-1127-patch-FixesClientApiPing.txt

uimaj-as-activemq-UIMA-1127-patch-FixesClientApiPing.txt
Removed method level synchronization on sendCAS and replaced it with a
dedicated mux object.
Fixed a bug in a client API that was causing a Ping message to be sent
immediately after Process timeout. The new code sends a Ping on a subsequent
CAS process request.
Modified testcase error handler to stop the client api on Ping Timeout.
> Services that timeout should be handled differently on subsequent requests

> When a request times out, the service should be put into a "questionable"
> state. Requests to a service in questionable state will then use a different
> logic: first send a getMeta request with a short timeout; if the getMeta
> succeeds, the questionable state is removed and the normal request is sent;
> if getMeta fails, an error is returned for the request with the state
> unchanged.
> This logic should be used for both API and aggregate clients.
