I've run into a NullPointerException when the AccessLogValve is configured to
log a cookie:

Here's the valve configuration:

        <Valve className="org.apache.catalina.valves.AccessLogValve"
          directory="logs" prefix="access.log." suffix=""
          pattern="%h %l %u %t &quot;%r&quot; %s %b &quot;%{Referer}i&quot;
&quot;%{User-Agent}i&quot; %{JSESSIONID}c %D %I"/>

RedHat has posted an article with the same exception noted:
https://access.redhat.com/solutions/1992003.  Unfortunately, the information is
hidden behind a paywall I don't have access to.  However I searched Bugzilla
and can find no evidence that they submitted a ticket upstream.

Thanks.
