When requesting a gif file the following exception is
logged. (Running in 
Tomcat 5.5). File is served OK, but exception is logged.
ArrayIndexOutOfBoundsException thrown by
PackagedServlet.service() (line 146). 
Section of code shown below:
  byte[] buffer = new byte[1024];
  while (in.available() > 0)
  {
    int len = in.read(buffer);
    out.write(buffer, 0, len);
  }

The len read from the input stream is -1 when the end is
reached. The available 
method only seems to start returning 0 after you have hit
the end of the stream 
by attempting a read that returns -1 (seems a little odd it
does not work 
correctly if you could only read < 1024 bytes in a
previous read call - looks 
like a problem with InflaterInputStream used for ZipFiles).
The write call throws the exception when len is -1.
I guess len should be checked before doing the write.
