Description

Both uima-as services and JPs are coded to report state information and JMX url back to the Agent. When launching a process, an Agent adds an env var where it passes its listener port.

When an agent is not launching a process, the port will not be present and DUCC service wrapper code throws an exception:

Modify code to test for presence of a port and if not available, disable state updates.
