For example:

https://docs.oracle.com/en/java/javase/16/vm/class-data-sharing.html#GUID-2942983A-E83C-4DA3-A60C-60411D731D5A

has links like:

http://www.oracle.com/pls/topic/lookup?ctx=javase15&id=application_class_data_sharing

but they should refer to javase16.

Looks like the Java 14 Guide had a similar problem linking to the Java 13 docs. Java 15 Guide links seem correct.
