-----------------------------------
Summary: UIMA-DUCC: Agent JMX connection retry not working
Key: UIMA-5659
URL: https://issues.apache.org/jira/browse/UIMA-5659
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.2.0-Ducc
When an agent looses a JMX connection to a remote service it does not try to
recover it. Instead just reports 0's for GC values.
The problem is that it checks connection for null and only if true the
reconnect happens. In the failing scenario, the connection is established and
works for awhile than the connection fails due to a long GC in the service. The
connection object is stale (not null) at this point and reconnect does not
happen.
When a JMX failure occurs set the connection object to null forcing a
subsequent reconnect.
