-------------------------------------
Hi Sanjay,
I just have a quick look of the path, it looks like you add a cleanup to the
FileUtil, but I didn't found the place where you call it.
Can you give us more detail about unload the application?

> FileUtil.getDefaultTempDir() registers a JVM shutdown hook to delete the
> temporary directory it creates. We are using camel in a web application in
> Tomcat that gets dynamically reloaded as updates are available, so the JVM is
> normally never shut down. This is causing 'camel-tmp-*' directories to linger
> in $CATALINA_HOME/temp, and - more importantly - classloader leaks, which are
> a major problem for us.
> If the thread that gets registered as the shutdown hook were stored in a
> class variable, I could unregister it when the application is being unloaded.
