Yes, there are a few things, but in the build itself, we are down to a single config file today, so I would really appreciate if this could be figured out. I can provide the implementation for generating this, but I need to understand what the expected pattern is. From what I can see, it looks like $(sequence N, M) where N is the last LTS+1 and M is current JDK version. Then the string has "JDK N" in it. M is already well defined, so the only new input here is N, which we could move to the version numbers config file (make/conf/version-numbers.conf). Something like DEFAULT_VERSION_DOCS_API_SINCE=11. There is some additional boilerplate needed, and the sequence macro of course, but does this sound reasonable to you?
