OK, more information on this.  They are using the same environment as mine, except, they are
not using SSL.
They have no SSL connector defined, nothing listening on port 443 or 8443 or with SSLEnabled
set or anything.
Here are the connector entries from their server.xml:

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> 
<Connector address="" port="80" maxHttpHeaderSize="8192" maxThreads="50" enableLookups="false"
redirectPort="443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true"

I'm thinking it has to do with the SSLEngine being set to "on" in the APRLifecycleListener.
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
The question is why?
Will setting it to "off" cause any problems?
Anyone know why "on" is the default when there is no SSL connector configured by default?
