[patch] 6646584 Compound assignment with Byte, Short and Character

[Peter Ahé]

It is not a bug.  See http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.26.2 
  and http://java.sun.com/docs/books/jls/third_edition/html/conversions.html#5.1.7 
.  There is no unboxing conversion from int to, for example, Short.  I  
think this is deliberate, as it would require a narrowing primitive  
conversion from int to short and a possible loss of information.  See: http://java.sun.com/docs/books/jls/third_edition/html/conversions.html#5.1.3

Cheers,
