I've filed this as http://bugs.caucho.com/view.php?id=5120
Is it possible that this code is from a forward? I just closed a bug
where a forwarded form would try to double-read the content.
Otherwise, this looks new.
If you can create a tiny example POST that triggers the problem and send
it, that should help track it down.
I can recreate this quite easily, without any forwards. All that is
needed is a large enough (> 75 parts) form.
Might be worth noting: If you press Stop in the browser, the server side
execution coninues normally. Otherwise it times out after 120 seconds.
Example (posted in Mantis as well):
JSP:
<html><body>
<form action="/multipart" method="post" enctype="multipart/form-data">
<%-- 76 fails, 75 is ok --%>
<c:forEach begin="1" end="76" var="i">
${i}: <input type="text" name="just_some_field_${i}" value="foo" />
<br />
</c:forEach>
<input type="submit" value="Submit" />
</form>
</body></html>
Servlet:
@MultipartConfig(fileSizeThreshold = 1024 * 1024, maxRequestSize = 100 *
1024 * 1024)
public class MultipartServlet extends HttpServlet {
@Override
protected void service(HttpServletRequest request,
HttpServletResponse res) throws ServletException, IOException {
System.out.println("Content length: " + request.getContentLength());
final long start = System.currentTimeMillis();
try {
System.out.println("Getting parts ...");
final Collection<Part> parts = request.getParts();
System.out.println("No of parts: " + parts.size());
}
finally {
System.out.println("Done trying to parse; took " +
(System.currentTimeMillis() - start) + " ms");
}
}
}
</Mattias>
