    Description

      Customer(s) have been using this internal feature for performance and removing it in JDK 18 without a replacement yet has been noted by a Java developer.

       See thread:
      https://mail.openjdk.org/pipermail/hotspot-dev/2022-June/060945.html

      And panama-dev thread:
      https://mail.openjdk.org/pipermail/panama-dev/2022-June/017074.html

      We'll work with customers to find an appropriate replacement in Panama but for now, this feature is important for Java customers and needs to be restored with the deprecation message.
