On touch bar machines, IMKInputSession throws exception when switching focus back and forth to app.

THIS DOES NOT SEEM TO FUNCTIONALLY AFFECT APPLICATION, but it does throw an exception in normal use, so it will litter log files.

Steps

1. Start JVM MAC app.
2. Wait.
3. Switch desktops (like if your IDE is on a virtual desktop, switch to that)
4. Observe JVM output (see below for exception thrown).

It doesn't happen every single time, but is high repro rate and I've gotten it to trigger 4 times in less than 5 minutes in a single JVM Acorn app.

Don't think this is happening anymore. Needs verification.
