The pow(int) method added in jsr13 calculates the return value with

return new BigDecimal(intVal.pow(n), scale * n);

This scale calculation is not properly guarded against integer over/underflow, allowing for potentially very misleading results.  Additionally, the calculation of 0^n should probably be special-cased.
