- Fix unfinite loop in
org.apache.logging.log4j.flume.appender.FlumePersistentManager.send when the
thread is interrupted (Note : The loop has been completely removed since it
does not seems to serve any purpose)
- Preserve Thread interruption status on InterruptedException
- Add unit test for this case
