JDK-8138878 seems to be JSOM hacking into private field in 
java.awt.Toolkit. It is possible to discuss the issue on awt-dev and 
i18n-dev to see if the changing locale scenario is meant to work?

We'll look into JDK-8140477. Note that there has been deadlocks 
involving instrumentation going back to JDK 5 (when java.lang.instrument 
was introduced). I don't know if this one is in that bucket but 
generally agents need to be take great care when instrumenting code 
defined to the ext and boot loader (because the agent's classes are 
defined by the app class loader).

JDK-8140481 seem to be the module missing from the JDK 9 
build, it may not be specific to the Jigsaw EA builds.

This is something to ask on valhalla-dev, it might be too early for that.
