After some experimenting, it looks like the reason I'm seeing this and most people aren't is that I'm building JDK 10 with bootstrap JDK 9+150 ("--with-boot-jdk=/Users/dan/bin/jdk-9+150"). No warnings with a JDK 8 bootstrap. The warnings do persist under jdk-9+160.

I'm not sure what should be done about them, but here are the first few lines of my build log:
