[ http://issues.apache.org/jira/browse/IO-99?page=comments#action_12450687 ] Vera Mickaël commented on IO-99: --------------------------------
I don't know if a daemon thread prevents a classloader from being garbaged ? I worked for several days on classloader leaks, classloaders that are never garbaged because a system class or a container class keeps a reference on the webapp classloader. In memory dumps I can see that FileCleaner thread keeps references on my webapp classloader, this thread is referenced by the JBoss thread pool wich is a container class. I can't say if this thread is responsible for my classloader leak, my opinion is that it does (look links provided, the fist one) But this thread adds many references to a dump that is already difficult read (I use a modified version of jhat). A service in the API stopping the thread would really simplify the task of developpers like me working on classlodaer leaks. I will open an issue in commons.fileupload referencing this one, maybe this package have more concerns about webapp environments. http://opensource.atlassian.com/confluence/spring/pages/viewpage.action?pageId=2669 http://blogs.sun.com/fkieviet/entry/how_to_fix_the_dreaded Thanks to whole developpers team for their work > FileCleaner thread never ends and cause memory leak in AS > --------------------------------------------------------- > > 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 Mickaël > Priority: Critical > > FileCleaner opens a thread and no solution is given to the user to end it.
