Before JEP486, some code used VM.getSavedProperty instead of System.getProperty to avoid circularity issues with custom security managers, see an example in this post-JEP486 cleanup PR: https://github.com/openjdk/jdk/pull/22141#discussion_r1844121917

Now that custom security managers are no longer a thing, uses of VM.getSavedProperty should be examined to see if they can be replaced with System.getProperty.
