Meant to include jigsaw-dev in the initial post.

serialver and javap are in jdk.compiler that is an appropriate home for jdeps while I don’t particularly like it since it isn’t clear to tell from jdk.compiler module name where jdeps is there.

The tool modules have been evolved a bit and some tools are put in its own module such as jdk.pack200, jdk.policytool, jdk.javadoc, jdk.jconsole, jdk.rmic etc.  that are organized around its primary tool which is easy to name, document, and understand.

Putting jdeps in jdk.jdeps module makes it easy where to find jdeps that is an attractive option. 

This also opens up the option to move jdeps to jdk repo in the future - it is just a side point and jdeps is currently being used as an interim solution to verify module boundaries until the module system is moving further along.

I will post a revised webrev.

Yes - we should re-visit this for the launchers we have.
