Thanks, Archie.

So, I've:

 - added a few more @SuppressWarnings, as needed
 - removed the `this-escape` disablement from `jdk.compiler`, `jdk.jdeps` and `jdk.jshell` (because all cases should be suppressed using @SuppressWarnings, I hope)
 - removed the `this-escape` disablement from the langtools build config
