[RFC] netx: search for main method in superclasses of the main class

[Omair Majid]

Hi,

The attached patch makes netx search for the main method in the 
superclasses of the main class. This patch allows JOSM [1] to work with 
Netx.

Some applications like JOSM declare a main class which does not contain 
a main method - the main method is declared in a superclass instead. The 
tar file attached contains a simple example of such an application. With 
the current version of netx, it throws an exception, saying that the 
main method can not be found. The attached patch moves some the method 
lookup code into a findMainMethod() which also loops through the 
superclasses looking for the main method if it is not found in the 
declared main class.

Any comments or concerns?

Cheers,
Omair
