     You could buffer to a ByteArrayOutputStream.

   InputStream source=getSystemResource(name.replace('.', '/') + 
".class").openConnection().getInputStream();
   ByteArrayOutputStream buffer=new ByteArrayOutputStream();
   try {
      for (int input; (input=source.read())>=0; ) {
         buffer.write(input);
      }
   } catch (IOException i) {
      Whatever
   }
   byte[] classData=buffer.toByteArray();
