Hi,

kawa failed to compile throw exception statement inside define-simple-class:

bash-2.05a$ cat Test.scm
(define-simple-class Test1 ()
 ((test) :: <String>
  (primitive-throw (make <java.lang.Exception> '|test|))
  )
 )
bash-2.05a$ kawa -C Test.scm
(compiling Test.scm)
java.lang.ArrayIndexOutOfBoundsException: -1
   at gnu.bytecode.CodeAttr.topType(CodeAttr.java:217)

I checked in a fix for this, in gnu.kawa.functions.Convert.

A more general solution would check things like:
  (func (primitive-throw ...))
This currently causes a compiler exception; instead we
should probably emit at least a warning.
