Is every Java method really a varargs method?

I don't believe that is the case. On the other hand, we've only tried
it on machines where the varargs ABI is the same as the non-varargs one.

I don't know the ARM ABI or assembler language, so I can't help.
Are you compiling with -O?

I don't beleive the overhead you fear exists, at least on the sparc.
(Of course, it has register windows.)
