Problem with collectArguments on primitive array type

[John Rose]

Hi Atilla.  It's a bug.  The collector created in  
sun.dyn.MHI.collectArguments (from ValueConversions.varargsArray)  
creates an Object[] unconditionally; it needs to be generalized to  
other element types.  In the backtrace you are seeing, F4.invoke_C2  
has applied 'filter' to the two incoming boxed ints and gotten an  
Object[] instead of the int[] required by the 'target', which is a  
wrapper (via A3.invoke_I3) for your strongly-typed xv function.
