Same here. :-)

I think they are pretty much the Java equivalent of *.ar.

Ah, I see.  I wanted noinst_JAVA, thanks.

The sources contain a 'package gnu.inet.encoding;' statement.  The
java compiler puts such files into gnu/inet/encoding/$class.class by
default.

Perhaps it might be good to state that "packaged" *.java files are not
supported by the JAVA directive, or add some logic to discover which
*.class files are generated from each *.java file.

Thanks,
