Classloader leak on FileUtils.createTmpDir()

            Slackware Linux 14.1 (kernel 3.10.17), Java 1.7.0_75, Tomcat 7.0.39 (this is my production environment)

            Description

            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.
