Experience has shown that most instances of this type of error are triggered by
application bugs rather than Tomcat bugs - usually in the form of retaining and
re-using a reference to the request or response object. One way to test this is
to set the system property org.apache.catalina.connector.RECYCLE_FACADES to
true. If you see NPEs then that is indicative of an application bug.
Something else that would be very useful since you are able to reproduce this
(albeit rarely) is a Wireshark trace of a connection where this occurred. If it
is a Tomcat bug it is likely to be triggered by an error condition in a
previous request on the connection.
It is worth updating to the latest 7.0.x in case you are seeing a variation of
bug 50189.
Ultimately, without more information that points to a Tomcat bug this is going
to get resolved as WORKSFORME.
