Part of the issue seems to be that the meaning of -Wno-unused seems to have changed and/or become ineffective. It's reported that it previously hid all unused parameter warnings though it doesn't seem to on any compiler I'm currently using.

I've included -Wno-unused-parameter with the changes going in JDK-8030350 so you should soon see the number of these warnings greatly diminish.
