[jira] Commented: (IO-99) FileCleaner thread never ends and cause
memory leak in AS
[ http://issues.apache.org/jira/browse/IO-99?page=comments#action_12455206 ]
Stephen Colebourne commented on IO-99:
--------------------------------------
The simple solution is to add a method exitWhenFinished() that sets a boolean flag.
The reaper thread then checks the boolean flag to see if it should stop the thread (once all tracked objects have been dealt with)
{code}
if (exitWhenFinished && trackers.isEmpty()) {
return; // terminate thread
}
{/code}
Code can then call FileCleaner.exitWhenFinished() from their servlet destroy method.

> Key: IO-99
> URL: http://issues.apache.org/jira/browse/IO-99
> Project: Commons IO
> Issue Type: Bug
> Affects Versions: 1.2
> Environment: JBOssPortal with commons.fileupload
> Reporter: Vera Mickaƫl
> Priority: Critical
>
> 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.
