Do you think it will break JS/Java bindings?

FYI:
I just got mojo_js_unittests compile and pass with GN+new EDK. It is now running
on FYI bots:
http://build.chromium.org/p/chromium.mojo/console

I will need to enable it on chromium bots and try bots.

Unfortunately I haven't got a chance to enable Java unittests. At least if the
resulting Java code cannot compile we will receive some chromium bot failures, I
think.

My plan is to look into the enable Java unittests when I get back.
