Thank you @gnu-andrew ! As to the copyright, in the current (before the fix) version of jdk8u it is virtually the same as in 22fad6452 new part of the 1st Keywords.java hunk (and in 11u) barring some formatting difference (lines are shorter in 11u). I've used 22fad6452 so decided to skip the hunk altogether (the old part of the hunk differs significantly).

The fixupFunctionTable() part, yes, I've missed it, thank you, retesting locally first...
