That's a wierd behviour, but it never produces incorrect results (it throws an exception when it would).
the two-argument versions of + - * / get inlined to a static method call. Either to a static method which accepts unboxed primitives or one that accepts their boxed variants. The problem is that the primitive versions return primitives and thus cannot overflow to Bignums, so they throw an exception. This 'bug' is unsolvable for now (until we get Fixnums on the JVM) without sacrificing the speed of primitive math.
