Re-opening to change fixVersion from 2.2.0 to 2.2.2
> 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. When the JMX fails to fetch GC info the GC collection
> should set GC values to -1. This info will be sent to Duccmon where the
> failure can be visualized. Perhaps changing color of GC value to red could
> alert a user.
