I understand that the SA already append the two, and that previously the prefix was a constant, but I don't see why the user would ever need to set the "prefix" when they can always specify a "unique_id" that is truly unique. What is the use case for this? ------------- PR: https://git.openjdk.java.net/jdk/pull/3669
