Description

Problem:

jdk9 b31 has excessively long execution time of MethodHandle.invokeWithArguments() method compared with b30.

Providing that invokedynamic instruction takes ~100 ms to execute the test code:

- In jdk9 b31 MH.invokeWithArguments() takes ~2000 ms
- In jdk9 b30 MH.invokeWithArguments() takes ~300 ms

-Djava.lang.invoke.MethodHandle.USE_LF_EDITOR=true solves the problem for me. It seems that MethodHandle.asSpreader() construction is what takes so much time. Caching considerably alleviates the problem (back to 2-3x slower than Method.invoke()).
