Error building from source on Mac

[Kevin Rushforth]

I presume this is Xcode 16? This is a bug in our code that we will need 
to fix.

GlassTouches is currently dead code and will either be removed or 
reworked at some point. See JDK-8238435, [2] which also has a comment 
from Martin Fox pointing out that this will no longer compile with Xcode 
16. This might be a good reason to do that.

As an FYI, we currently use Xcode 14 (14.3.1 to be precise) for our 
production builds and are in the final testing stages of updating to 
Xcode 15.4 to match JDK 25. See Draft PR 1798 [1], which I plan to take 
out of Draft early next week. We will at some point want to start 
building with Xcode 16, so we do want to fix this bug.
