Thank you for chiming in, @JohnHamer-Glasgow! (And welcome to JOL!)

I have a suggestion to remove `Author` and `Created` lines from this file, because it does not match the style of other files in the project, and this might be lost by accident, or otherwise raise questions during the review. For example, if we ever divide/delete `LJV.java`, it would be hard to judge where these comments should go.

There is a tangential rule that we try to avoid `@author` javadoc tags, to be consistent with OpenJDK code style. I think John is now recorded as developer in project properties, which is cleaner, better, and gives John the credit for the entire project, not just single file.
