Subject [jira] Resolved: (IO-99) FileCleaner thread never ends and cause memory leak in AS
Date Fri, 29 Dec 2006 13:12:27 GMT
     [ http://issues.apache.org/jira/browse/IO-99?page=all ]

Stephen Colebourne resolved IO-99.
----------------------------------

    Resolution: Fixed
      Assignee: Stephen Colebourne

I took a look at getTrackerCount(), but its already synchronized because the list is a Vector.
I added a few comments about synchronization to the file to help clarify.

Closing the call as fixed.

> FileCleaner opens a thread and no solution is given to the user to end it. So when an
application is undeployed
> in an Application Server, a thread is still alive. The WebApp can't be undeployed and
this results in a classloader
> leak that will cause an OutOfMemoryError.
> I think the API should be extended so that a user can end the thread. A better way would
be to provide a class that
> cleans everything for commons IO.
