PROPOSAL: Simplified Varargs Method Invocation

[Reinier Zwitserloot]

Mark,

good find. It turns out that you can use varargs to invoke a method  
with signature:

public void methodName(Foobar[] x) {}

*IF* any supertype of the type containing this method has the same  
method with varargs. I assume that's why the warning was removed. This  
magic varargs behaviour is present in both javac 1.5 and javac 1.6.
