Thanks to you both for working on this issue.
This works for now, but I hope you won't mind if we rip it out again for
0.13. One Thing I don't like about this is that it creates a new compile
time constant which makes it harder to share an GNU Classpath glibj.zip
class byte code between runtimes installed on the same system. I would
like to see something like the following for breaking up the
initialization of java.lang.System into two phases in the future:

 boolean explicitly_initialize = VMSystem.explicitlyInitializeStatics();
 if (explicitly_initialize)
   {
     initLoadLibrary();
     initProperties();
   }

That way a runtime could introduce its own VMSystem, but still share the
system installed glibj.zip.

Both David and Jeroen made a couple of good suggestions for improving
the runtime/platform interface. We should work on that more in the
future. It will also help with the libgcj and kaffe integration since
the bits that haven't been shared completely yet are precisely these
kind of system/bootstrap classes.

Cheers,

Mark
