First, most of these are in rhug already.
Second, you don't need to remove the main methods.  It is perfectly
fine to have a class with a main() method in a library.

Or use the command-line options.  Generally I prefer these over
setting the environment variable.

I believe there is some support for putting .jar files into a standard
directory where they will be searched by default.  I haven't kept up
with this area very well; maybe that is still just a plan...?

I don't know.  I don't think I have enough information to understand
the problem.  Is this another instance of our ongoing org.w3c.*
difficulties?  That is something we need to clear up for the 3.3
release.

If you're using gcj, libgcj.jar is searched automatically.
And anyway libgcj.jar shouldn't be run through the verifier, since
none of the methods in it should be compiled when you compile your
program.  What exactly are you doing?  How exactly does it fail?

I saw your PR on this come in but I haven't read it yet.

I recommend contacting the rhug project and coordinating there.
