-  $HOME/jdk/jdk6

   $HOME/jdk/jdk8
   $HOME/jdk/jdk9

   Alternatively, define ant variables thus:
-  ant -Djdk$N.home=...
-  for $N in 6 7 8 9 ...
+  ant -Djdk$N.home=... -Djdk$N.src.home=...

-  Build for jigsaw using something like:
-  ant -Djdk9.home="$HOME/jdk/jigsaw" -Djdk9.src.dir="$HOME/jdk/src/jigsaw" clean test dist
-  "docs" target is still broken.
