回答1:

I had the same issue with the latest sierra update - try downloading JDK 9 (download here)

回答2:

I solved my issues by downloading a pre-release of Java. I was having trouble with Attachmate's Reflection for the web. The Java bugs seem to be corrected in Version 8 Update 122. Earlier, I had tried Version 9, but it seemed a little buggy.

The official Oracle release tells you how to fix it:

JVM throws NullPointerExceptions on macOS Sierra 10.12 On macOS Sierra 10.12, if a user presses modifier keys (such as Command, Alt, Shift) while an applet is running in a browser, an error box named “Internal Error” might be displayed. It will also show the “exec” icon in the macOS dock. The user can dismiss the applet, or try to rerun the applet while not pressing a modifier key. To fix this problem, install JRE 8u112, for Mac OS X.

To me it happens that it crashes only if I press the shift or the capslock keys...and if I insist confirming "continue" in the warning message for 6,8,10 times it starts working normally...my procedure (not happy with it, just as a temporary solution expecting this bug to be fixed): I press capslock and I leave it on (have to click "continue" in the crash warning). Then I press several times shift and at each time I click continue...it fixes after 4-6-8 times....hope it helps.

Installing macOS Sierra 10.12.1 beta 3 has fixed it for me. If you're not in the beta program, you could monitor when it's publicly released.
