Sun Reflection Provider

There is an implementation of ReflectionProvider that relies on some Sun internal classes to speedup reflection by bypassing security checks. This provider may be 25% faster than the default provider depending on how you're using mirror. Warning!!! This will probably only work on Sun JVM 1.5 and 1.6. There are two ways to use it:
new Mirror(new Sun15ReflectionProvider());
or add the following line to your
provider.class = net.vidageek.mirror.provider.sun15.Sun15ReflectionProvider
