Resolution
Remove the ipv6 tomcat connector by remarking or deleting the following line from "/etc/tomcat/server.xml":
<Connector URIEncoding="UTF-8" address="::1" connectionTimeout="900000" maxThreads="650" port="8009" protocol="AJP/1.3" redirectPort="8443"/>
Cause
From tomcat the ipv6 connector is enabled, however ipv6 is not enabled / active for the network interface.
