How to get the "main" class?

[Eric Caspole]

It seems not so outlandish that most profilers/monitors/debuggers etc  
would want to be able to retrieve and present this to the user of the  
tool, if only so that you could monitor 2 things at once and easily  
see what's what without having to look up the pid. But it sounds like  
it might be done by some custom magic for each tool.

Is there any path to standardize finding the main class when using  
the normal launcher? I know it would not apply the same way when  
doing JNI_CreateJavaVM by hand in app code but it seems useful in  
many cases.

Regards,
Eric
