Classes from Orion JAR are not usable in server

[mikroskeem]

One good example is feature/disable-player-data-saving branch. Server dies off with IncompatibleClassChangeError error

Very likely that event classes and such are affected from this problem.

Debug event listener mechanism had clazz.asSubclass(Event.class) and that threw ClassCastException though.

I did some debugging and got this this:

Server classes:

• MinecraftServer classloader: net.minecraft.launchwrapper.LaunchClassLoader@3c130745
• IPlayerFileData interface classloader: net.minecraft.launchwrapper.LaunchClassLoader@3c130745
• current IPlayerFileData implemetation classloader: net.minecraft.launchwrapper.LaunchClassLoader@3c130745

  After replacement:

• new IPlayerFileData implementation: sun.misc.Launcher$AppClassLoader@42a57993
• Orion IPlayerFileData ...class.getInterfaces()[0].getClassLoader(): sun.misc.Launcher$AppClassLoader@42a57993
