Collecting finbugs analysis results randomly fails with exception

      It started some weeks ago that jobs with long running findbugs tasks started to fail while collecting the results. So every morning I have to restart a job or two to get everything back to blue.

      This exception seems to be random. It only ever occurs while the findbugs plugin is running and not during any other static code analysis. Any plugin that runs afterwards fails with a similar message that the connection is closed.

      Another strange thing is that afterwards I can't see the slave log anymore. All I get is the wait image on the page but no log ever loads again until a restart of the master. A simple restart of the slave node does not change anything although jobs are running fine.
