For the record, there are 2 work-arounds for this bug:
1/. Don't use connection tracking, use a "stateless" packet-filter rule instead
    eg on the tomcat-server
       iptables -A INPUT  -p tcp -s apache-server --dport 8009 -j ACCEPT
       iptables -A OUTPUT -p tcp -d apache-server --sport 8009 ! --syn -j ACCEPT

 -- or --- (nicer)
2/. tweak the setting:
       echo 5 > /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_max_retrans
