11924	Add compatibility with Java 9	Don-vip	team	"Java 9 is well advanced in its development, early builds are now available. [http://openjdk.java.net/projects/jigsaw/ Jigsaw project] is now merged into main tree.

I have added basic Java 9 support in r8777:8778, r8793, r8795, r8796:8797 but making JOSM work with Jigsaw is another challenge.

This ticket aims to list all problems encountered.
