Regular Java Crashes under macOs Sierra

[Mark Derricutt]

HI all,

I'm noticing a bunch of core JDK crashes using the 8u112 dev builds when running IntelliJ IDEA under the new macOs Sierra:

```
Exception Name: JavaNativeException
Description: java.lang.NullPointerException
	at sun.lwawt.macosx.CAccessibility.getAccessibleIndexInParent(CAccessibility.java:289)

Is this an appropriate place to post about this?  Known issue?
