If you're using ClassLoader.getResourceAsStream() each time you check the 
config, it should be o.k. without a restart.  However, if you're using some 
technique that caches the config with the classloader, it won't go away until 
the classloader does, which won't be until the complete JVM is restarted.

It's not quite the same, in that there's a separate classloader that handles 
java.endorsed.dirs, rather than the system classloader.  For these purposes (no 
classes), the difference is probably moot.  I'd still likely use 
java.endorsed.dirs, just to keep things separated.

As long as no actual classes are involved, I don't think there's a problem.
