         I'm a Java newbie, so please pardon if I'm missing something
    glaringly obvious. But I've done some Googling and haven't been able to
    figure out what's going on.

         I'm trying to write a Java applet for image display. No big deal,
    seems like a nice first Java project. I'm using the 1.4.1 SDK on Linux
    with the "target=1.1" option to javac to try and make it work with old
    browsers (our target demographic is likely to have older boxes and
    machines). Which makes me use AWT instead of Swing and makes the applet
    ugly, but c'est la vie.

         The applet loads fine in my browser (using the 1.4.1 JRE plugin)
    and I'm told it loads ok in IE 5.5's built-in 1.1 VM. However, when
    using old versions of Netscape, I get an ExceptionInInitializerError
    exception with getException().getMessage() as "sun.io.CharToByteUTF-8".
    The exception is thrown when I try to get the InputStream from a
    URLConnection; however, I'm able to get the ContentLength and
    ContentType from the URLConnection without a problem, so I know it's
    opening and reading from the TCP connection.

            URL u=new URL(getCodeBase() + "image.bin");
            debug(u.toString());
     
            URLConnection uc=u.openConnection();
            debug (uc.toString());
     
            uc.connect();
           
            int filesize=uc.getContentLength();
            debug (filesize);

            // ContentType is application/octet-stream
            debug (uc.getContentType());
     
            // exeption thrown here...
            InputStream rawstream=uc.getInputStream();

         My Googling leads me to the impression that there's a bug in the
    Netscape 4.7x VM regarding the class name, something like
    sun.io.CharToByteUTF-8 versus sun.io.CharToByteUTF8?

         Can anyone tell me more about this? Any work-arounds (besides
    getting people to upgrade their browser?) or suggestions? Much gratitude
    for any assistance.
