             Summary: FilesystemAlterationMonitor.delay is not safely published
                 Key: JCI-74
                 URL: https://issues.apache.org/jira/browse/JCI-74
             Project: Commons JCI
          Issue Type: Bug
          Components: fam
    Affects Versions: 1.0
            Reporter: Sebb


The field FilesystemAlterationMonitor.delay is read by the daemon thread but 
the writer and reader do not use synchronisation.

If the delay is changed after the thread is started, any changes may not be 
seen by the thread (unsafe publication).

The delay field needs to be made volatile.
