Summary: UIMA-DUCC:make DUCC_STATE_UPDATE_PORT optional
Key: UIMA-5718
URL: https://issues.apache.org/jira/browse/UIMA-5718
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.2.2-Ducc
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.
