arity mismatch on a call to spreader method handle should elicit IllegalArgumentException

    XMLWordPrintable

Details

    Backports

      Description

        When an array is passed to a method handle transformed by MethodHandle.asSpreader, the array must have exactly the number of arguments expected by the original method handle. If the array length is wrong, the result should be the same as if the wrong number of arguments were passed to the original method handle.

        This is a gray area in the JSR 292 spec.

        (Note: The first version of this bug report read WrongMethodTypeException instead of IllegalArgumentException. The JSR 292 EG has agreed that IAE is more appropriate for this error.)
