[drlvm] [classlib] Running specjvm98

Hello

I've tried to run specjvm98 on Linux on drlvm and encountered several problems 
with it. I've created JIRA HARMONY-644 with those which I could resolve, I 
don't want to repeat what I wrote in comments there already.

I have several questions yet after it.

1. Is it ok to modify Applet to extend Panel? I am entering not a well known 
for me territory of classlib in the current state, so I am not sure if I 
don't break something with it.

2. What is VM.bootCallerClassLoader() is supposed to return? If I understand 
it correctly from the comments it should return bootstrap class loader 
object. But I always thought that it is null by specification.

3. Spec still doesn't run, it now fails on

Uncaught exception in AWT-EventQueue:

I didn't find this library, perhaps I am missing something... Where is it 
supposed to appear from? Is it native code from awt/swing which wasn't merged 
to build from the contribution yet?

It seems that still harmony-528 is 'in progress', contributed
awt/swing natives are not merged yet (this liblrary really should
appear from that code) and one cannot execute awt-based  code.
