  Slow performance when using custom classloader in applet.  (Read 1908 times)

I've been trying to implement a custom classloader with applets but I'm having some performance problems.

If I create the classloader with the ClassLoader.getSystemClass() as parent, using defineClass (with bytecode) is fast. Problem then is that the instances I create from classes defined cannot find any class defined in the classloader used with the applet class.

When I use the  classloader from the applet class as parent in my custom classloader, the performance of defineClass get very slow (like 3-4 defineClass pr second).

I'm currently using the first method and using reflections to get around the problem, but it's a bit hacky, so any suggestions would be appreciated.
