--------------------------------
Summary: StopWatch.getDuration produces incorrect results
Key: NIFI-5742
URL: https://issues.apache.org/jira/browse/NIFI-5742
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 0.8.0
Reporter: Tim Harsch
getDuration will produce unexpected results when the StopWatch has been stopped.
See:
https://github.com/apache/nifi/blob/02261311b3b3f765ebb394f8f101b0373a7fb3ab/nifi-commons/nifi-utils/src/main/java/org/apache/nifi/util/StopWatch.java#L77
Currently, if the stopwatch has been stopped it returns the current nanos since
epoch - (-1), which is meaningless at best and likely to cause issues for
applications using this method.
It should either return an exception because the elapsed time has no meaning
after being stopped, or return the elapsed time when the watch was stopped, or
just keep going and return the current value.
