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

There is some TBD here, most likely the file system will need to provide 
file paths to get to the class files without knowing the module name.

The workaround for tools don't know anything about modules yet is to 
just construct a class path of /$MODULE/* . The additional searching 
might mean a bit of a performance hit but should be equivalent to 
today's searching of ${java.home}/**/*.jar.
