>                 URL: https://issues.apache.org/jira/browse/CXF-6749
>             Project: CXF
>          Issue Type: Bug
>    Affects Versions: 2.7.14
>         Environment: Slackware Linux 14.1 (kernel 3.10.17), Java 1.7.0_75, Tomcat 7.0.39
(this is my production environment)
>            Reporter: Diogo Sant'Ana
>            Assignee: Daniel Kulp
>              Labels: classloader-leak
>             Fix For: 3.1.5, 3.0.8
>
>
> FileUtils.createTmpDir() adds a ApplicationShutdownHook to remove the recently created
temp folder, creating a indirect reference to the Tomcat WebappClassloader from the hook static
attribute at ApplicationShutdownHooks class, preventing the classloader to be collected.
> Actually, it will be collected when the JVM is turned off. But this is a web application
container, it won't be turn off for a while.
> I only checked this with the version I´m currently using (2.7.14), but I checked the
code at 3.1.x and master branches and it still the same.
