bug32051.war

A war file that contains reproducer classes, as submitted by Dario Franceschi,
compiled with Java 6.

Steps to reproduce:
1. Deploy the war
2. Access http://localhost:8080/bug32051
A simple HTML page with word "hej" is displayed in browser.
3. The INFO message from CoyoteAdapter.checkRecycled is printed on the console

It reproduces for me with current Tomcat 8 (trunk @r1627265) with every one of
4 connectors (Bio, Nio, Nio2, Apr) using JDK 7u67 (32-bit) on Windows 7.

It does not reproduce for me with current Tomcat 7 (tc7.0.x @r1627245) with any
of 3 connectors (Bio, Nio, Apr) and any of {JDK 6u45, 7u67} (32-bit) on Windows
7. The page is displayed and there is no log message.

Context listener

If you omit the close on the printwriter the socket will be RST before the data
is transferred causing for instance wget to re-submit

Context listener

Thanks for the WAR Konstantin. I see this on OSX. It looks to be OS neutral to
me.

I'll note that the AsyncListener should be calling AsyncContext.complete() at
the end of onTimeout() which may avoid this error. Irrespective of that, this
is still a bug that needs to be fixed.

Seems I only get this on windows 7 (64) and tomcat 8 ( tried 8-11 & 8-12 ) on
tomcat 7 I do not get this, I do not get this on tomcat 8 on (32 bit) linux
either.

Have also tried Java7 & Java8 but that does not seem to be related.
