I haven't seen any proof that those three ports actually belong to the
same process. It is likely, I grant you, since they are the defaults but
with re-packaged installs you never know.

If those ports are all owned by the same process, no. Something else
must be up. Could be IPv6 related but no idea what.

Some Tomcat logs would be nice.
