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.

It throws:
Exception in thread "main" java.dyn.WrongMethodTypeException:
[Ljava.lang.Object; cannot be cast to [I
at sun.dyn.FromGeneric$A3.invoke_I3(FromGeneric.java:543)

Seems it has troubles collecting arguments for an int[] vararg.
Attila.
