Chuck & André -
Back about this time last year, I noticed this on my first Windows 2008 Server
install.
It was Tomcat 5.5.27 with Native libraries 1.1.16 and Sun JDK 1.6.0_13 (all
64-bit). I really think it has something to do with APR, though I haven't
tested it without the native lib. My solution was to specify the IPv4 address.
Add to that the server.xml only has the one <Connector> entry, so I think it's
setting up only on the one address.
Here are the relevant portions of the server.xml:
<Server port="8005" shutdown="SHUTDOWN">
<!-- Comment these entries out to disable JMX MBeans support used for the
administration web application -->
<Listener className="org.apache.catalina.core.AprLifecycleListener" />
<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />
<Listener
className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener
className="org.apache.catalina.storeconfig.StoreConfigLifecycleListener"/>
<!-- Global JNDI resources -->
<GlobalNamingResources>
<!-- Test entry for demonstration purposes -->
<Environment name="simpleValue" type="java.lang.Integer" value="30"/>
<!-- Editable user database that can also be used by
UserDatabaseRealm to authenticate users -->
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>
<!-- Define the Tomcat Stand-Alone Service -->
<Service name="Catalina">
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector
port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009"
enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
And here's the relevant netstat output:

Notice that the Server port went specifically to localhost, but the other two
went to the IPv6-any address. The same occurred for the 32-bit version.
When I started the 32-bit setup with the APR 1.1.4 that was initially
downloaded, the Connectors went only to the IPv4-any address. I guessing that
1.1.4 doesn't support IPv6 at all.
When I started the 32-bit setup without the APR native binaries, then I saw the
behavior you state should be occuring:

So my conclusion is that the APR library, at least at 1.1.16, only opens one
connection per connector. Or perhaps Tomcat is only opening 1 connection when
it takes the APR support code path.

Note: I didn't try the no-native 64-bit because I have other production
instances using the same Catalina_base/bin directory.

May I jump in to add somewhat to the question ?
Thank you.
Can someone explain this a little bit more in detail, or point to some
rough explanation page somewhere ?
Basically :
- why did that Tomcat 5.5.29 "listen only on IPv6" until it was forced
to IPv4 by specifying "0.0.0.0" in the Connector ?
- why, when Tomcat is listening (only) on IPv6 [::]:8080, does it not
accept telnet connections on port 8080 ?
- why, when Tomcat was listening (only) on IPv6 [::]:8080, did HTTP:8080
connections from a browser on localhost work, but not the ones from
other stations ?
- can you set Tomcat to listen on /both/ IPv4 and IPv6 on port 8080 at
the same time ?
Thanks for any pointers.
