java.desktop and all its dependencies are recompiled.   The dependencies
are currently stored in modules.list file

$ grep desktop <top>/make/common/modules.list

Erik's summary of the new targets is a useful reference:
http://mail.openjdk.java.net/pipermail/jdk9-dev/2014-August/001183.html

See also -only, -java, etc suffix to the java.desktop target that may be 
useful.

JDK_FILTER should still be working.
