[Bug-kawa] [bug #49537] 'format' on String[] (supported?) prints only first

[Per Bothner]

Follow-up Comment #3, bug #49537 (project kawa):

A Java varargs methods that takes (S s, T... ts) is compiled to (S s, T[] ts).
 For compatibility reasons, Java allows such a method to be called *either*
with an array or flattened: (s, ts) or (s, t1, t2, t2), where ts == {t1, t2,
t3}.  The latter is basically compiled into the former.

For compatibility (again), Kawa allows either when calling a varargs method. 
A varargs method is either one written as such in Java, or a Kawa method with
a #!rest parameter whose type is specified to be an array (rather than a
list).

There is obviously an ambiguity when T==Object and the number of varargs
arguments is 1.

See the explicitArrayAsVarArgsAllowed fied in PrimProcedure.java. I think
you'll find if you change that to false, the weird behavior goes away. I'll
probably change it to false for Kawa 3.0 (based on the invoke branch).
