I came across an interesting tidbit that generally results in OOM Perm Gen.
Any code that calls File.deleteOnExit() should not be used in a server environment. basically, every deleteOnExit() uses some memory to track the file and its order for deletion. That memory is not freed until the JVM shuts down (even if the file is deleted). There is no way to turn the flag off once it is enabled. So in a system that "never" shuts down usage results in memory exhaustion. So now, my question is for the code we are testing are there File.deleteOnExit() calls? Are we using the method in the test code itself?
