If the patch was committed to jdk/jdk or jdk-updates/jdk11 (as opposed
to being an older jdk9 patch), it usually needs both the jdk11 script
[0] (to move the files back into their subrepos, jdk11->jdk9) and the
jdk9 script [1] (to get rid of the modules, jdk9->jdk8). Both scripts
need data files from the same directory, so checking out the repos is
probably the easiest option.

All this file movement is a major PITA.
