With the tip build of jdk9-dev forest, nashorn's "ant clean test" fails. One of the failures shows the following stack trace:

Note that the same nashorn repo's "ant clean test" passes with jdk8 update 31 on Mac as well as jdk8 update 40 early access build (32 bit) on Ubuntu. So, this is definitely a j.l.invoke change that causes this.

There are other tests that fail with the same AssertionError as well.

This is P1 because this issue prevents Nashorn nightly run as well as developer testing of nashorn with jdk9-dev forest build.
