This is difficult to answer. We have been trying to do JDK 9 testing,
but the early access builds have been "broken" from our perspective
all summer long, so we had to disable them because developers were too
confused when tens or hundreds of tests fail.

The major problems were various bugs in System.arraycopy...

Because of that, this one might be a general JDK 9 problem unrelated
to jigsaw. I'll have to spend more time digging into all those items I
listed to try to see exactly what is happening, but those were the
issues I hit when trying to get the jigsaw build to pass the tests.
