Catalina log
Hi,
when Tomcat is under load from an Apache httpd server (through mod_jk and
ajp13) and I shutdown it, I get NullPointerException:
^C
23-ago-2010 11.06.47 org.apache.coyote.http11.AbstractHttp11Protocol pause
INFO: Pausing Coyote HTTP/1.1 on http-9080
23-ago-2010 11.06.47 org.apache.coyote.ajp.AjpProtocol pause
INFO: Pausing Coyote AJP/1.3 on ajp-9009

INFO: Stopping service Catalina
23-ago-2010 11.06.48 org.apache.catalina.connector.CoyoteAdapter service
GRAVE: An exception or error occurred in the container during the request
processing
java.lang.NullPointerException
at
org.apache.catalina.connector.CoyoteAdapter.postParseRequest(CoyoteAdapter.java:638)
at
org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:397)
at org.apache.coyote.ajp.AjpProcessor.process(AjpProcessor.java:450)
at
org.apache.coyote.ajp.AjpProtocol$AjpConnectionHandler.process(AjpProtocol.java:385)
...
I think the stopping of the Coyote AJP Connector doesn't work. In fact, if you
go with jconsole on MBean Catalina->Connector->8009 and do "Stop" on "operation
tab", nothing happens.
To reproduce this bug:
* Download Tomcat 7.0.2
* Confingure an Apache httpd with a JkMount /examples/*
* Use ab to generate request (ex: ab -c 3 -n 1000000
"http://localhost/examples/jsp/jsp2/el/basic-arithmetic.jsp")
Thank you,
Domenico Briganti

The NPE you are seeing is a side-effect. The root cause is bug 49497.
JMX not having any obvious affect is a separate bug. The connector is stopped
(the state changes) but nothing is logged and it will continue to work since
there is a mis-match in the state transitions between the Connector and the
underlying ProtocolHandler.
I have a patch for the start/stop issue but I want to take a closer look at the
Connector & ProtocolHandler life-cycles to see if I can align them.

This bug has been fixed in 7.0.x and will be included in 7.0.3 onwards.
Note: There is scope for further re-factoring to align the protocols and the
endpoints with the new life-cycle code in 7.0.x.
