Sorry about that, I assumed I was making a correction to a long standing
problem. When we build jdk update releases, the docs are not regenerated.
The variable JDK_UPDATE_VERSION indicates a jdk update build, I
just assumed that's what it was being used for.

Strange use of JDK_UPDATE_VERSION if you ask me.

Why not just 'make GENERATE_DOCS=true' with the IcedTea builds?
Or am I missing the point?
What exactly is it that JDK_UPDATE_VERSION provides for IcedTea builds?
