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.

And panama-dev thread:

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.
