Comment (by chrstphrchvz):

 This was [https://github.com/macports/macports-ports/pull/20051]

 My guess is that the comment meant to say that if a port’s build outputs
 have hardcoded filepaths from the `java.fallback` port, then set
 `java.enforce` for the port to always depend on `java.fallback`,
 regardless of whether Java already present on the system.

 If I understand the intention of this option correctly, then I do not see
 how it is desirable, and I am in favor of removing it. I agree with Nils
 Breun that such hardcoding in build outputs should be avoided.

 And as currently implemented, `java.enforce` does not actually force the
 port to build using `java.fallback`, because it does not force `JAVA_HOME`
 to point to `java.fallback` rather than some other Java installation.

 `java.enforce` is not used by any ports; it was only ever used in abcl,
 but not since an alternative was found: [https://github.com/macports
