FULL PRODUCT VERSION :
java version "1.4.2_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_01-b06)
Java HotSpot(TM) Client VM (build 1.4.2_01-b06, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
Given a method with a method-level generic type where the parameter list is variable length in the generic, any call to the method fails. See varArg2 in code below. I am hoping this is a problem with the early release of the generics compiler and not a "feature" of 1.5.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The calls to varArg2 below cause compiler errors.
