OutOfMemoryError in applet that just uploads files

Question

I have an applet that uploads files to the server and I'm seeing an OutOfMemoryError when the files are too large for the available heap size of the JVM. The code that uploads the files is rather straightforward:
   private static byte[] fileBuf = new byte[8192];
   URL url = new URL(url);
   URLConnection urlConn = url.openConnection();
   urlConn.setDoInput(true);
   urlConn.setDoOutput(true);
   urlConn.setUseCaches(false);
   OutputStream os = urlConn.getOutputStream();
   InputStream in = new FileInputStream(file);
   ProgressMonitorUpdater pmu = new ProgressMonitorUpdater(pm, totalBytes);
   // Read from the file stream and write to output stream
   for (;;) {
      int bytesread = in.read(fileBuf);
      if (bytesread < 0) {
         break;
      bytesTransferred += (long)bytesread;
      os.write(fileBuf, 0, bytesread);
      os.flush();
      // Update the progress monitor
      pmu.bytesTransfered = bytesTransferred;
      doUpdate(pmu);
   in.close();Why would this code eat up all available heap space if the file is too large? The ProgressMonitorUpdater simply issues a SwingUtilities.invokeAndWait to allow the progress monitor UI to update with the new byte count info. Should the FileInputStream or the OutputStream from the URLConnection be consuming space from the heap?
Any help would be much appreciated.
Thanks,
