(This Bug follows 4205 which is not marked FIXED)

On armv5tel-unknown-linux-gnueabi I compiled gcj plus .../contrib/download_ecj.

            System.out.println("Hello World!");                                 
        }                                                                       
    }                                                                           

    plug bin #     

I really feel badly having to come to you with my struggling; however, I have a
good deal of experience with Perl and some Java and find myself gated by what
members of this team think trivial.  Please keep in mind when someone comes to
try installing the gcc compiler and getting it to run, they do not have the
experience and day-to-day exposure you have, so something simple as an
incorrect path can be confounding. 

I'm not sure which class is missing (or not pointed to with the class path)
from the above output.
