Just a note... the fix for JDK-8304443 adds `@SuppressWarnings("this-escape")` to the compiler code, and that should also fix this bug as a side effect. This PR, which disables the `this-escape` lint warning, works too, of course.

So, just in case you change your mind and choose to NOT disable the `this-escape` lint warning, then for consistency's sake we should also re-enable it for the regular build in `modules/jdk.compiler/Gendata.gmk` and `modules/jdk.compiler/Java.gmk`.

My apologies for using two different approaches to suppressing the warning at different times.
