[jira] [Commented] (FILEUPLOAD-205) FileCleaningTracker Reaper thread not ended

["Thomas Neidhart (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FILEUPLOAD-205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13598205#comment-13598205 ] 

Thomas Neidhart commented on FILEUPLOAD-205:
--------------------------------------------

This is maybe related to this question at stackoverflow:

http://stackoverflow.com/questions/12301934/org-apache-commons-io-filecleaningtracker-does-not-delete-temp-files-unless-expl

It looks like in some environment, the DiskFileItem references are not gc'ed and thus the FileCleaningTracker has still trackers attached, thus the Reaper thread will not end after a call to exitWhenFinished (he is not finished yet).

> When using a new FileCleaningTracker and calling exitWhenFinished upon WebApp context deinitialization the thread is not shutdown. This can be easily reproduced by using Tomcat's "Find leaks" funcitonality.
