Re: JNI, applets and ClassLoader re-use

Cool. But instead of making multiple copies, wouldn't it be more efficient to save the library as a randomly named temp file (as Glen suggested last week in another thread), load the library into memory, then delete the temp file? And repeat on the off-chance that you pick the same random name more than once...
