Hello,
We recently came across a problem on our production environment where Resteasy was saving temporary files on '/tmp' without deleting. We upgraded the JBoss AS 7.1.1 Resteasy modules to 3.0.9.Final and httpcomponents module to the latest libraries httpcore-4.4.1.jar, httpmime-4.5.jar and httpclient-4.5.jar.
According to this Jira [RESTEASY-681] Temporary files are not deleted when using multipart requests - JBoss Issue Tracker the bug was fixed on version 2.3.3.Final, unfortunately we are still having the same problems
Any help is appreciated. Thank you.
