javac Modules code contains the following:

http://hg.openjdk.java.net/jdk9/dev/langtools/file/b5af83c995f9/src/jdk.compiler/share/classes/com/sun/tools/javac/comp/Modules.java#l166

        // The following is required, for now, to support building
        // Swing beaninfo via javadoc.
        noModules = options.isSet("noModules");

This needs to be cleaned up.
