This might be relevant (or rather the link near the top to the Sun bug 
database):

http://mail-archives.apache.org/mod_mbox/tomcat-dev/200511.mbox/%3C4375392B.7000306@cognitiongroup.biz%3E

and this JBoss wiki entry says it a bit better wrt releases up to JDK 5:

http://wiki.jboss.org/wiki/Wiki.jsp?page=IPv6

So maybe try:

java -Djava.net.preferIPv4Stack=true ...
