While testing 8.5.48, we now see NullPointerExceptions when our
ImageServlet code attempts to forward a request to a new location. In
8.5.47, the code works fine.
A simplified version of our code:
public void sendResource(HttpServletRequest request,
HttpServletResponse response) throws IOException, ServletException
{
request.getRequestDispatcher(getForwardLocation(request)).forward(request,
response);
}
The NPE stack trace we see:
java.lang.NullPointerException

Let me know if you'd like me to open a Bugzilla and/or provide more context.
Thanks,
