Support for jrt-fs.jar in JDK 7 would be very helpful in allowing FindBugs to run under Java 9

We're trying to move away, as much as possible, from encouraging
developers to rely upon the existence and content of specific files
inside a run-time image.

Exposing the package-to-module map via the NIO filesystem API is clean
and relatively simple.  It might be a little less efficient than using
a separate properties file, but I don't think utmost efficiency is the
ultimate goal here.
