I made some more tests and I think my problem is due to a
Java/FreeBSD/IPv6 incompatibility of some sort which prevents Java to
fallback to the IPv6 representation ::ffff:127.0.0.1. When I run a
test-app (which I took from another thread regarding this topic, see
below) on a Linux machine it actually behaves as expected and binds to
the address ::ffff:127.0.0.1. However, when I run it on any of my
FreeBSD machines with an IPv6 capable JVM, it throws exactly the same
BindException as the Tomcat when trying to create an IPv6 address from a
given IPv4 representation.
import java.net.*;
public class TestServer {
public static void main (String[] args) throws Exception {
if (args.length != 2) {
System.out.println("Usage: java TestServer
<host_address_ipv6> <port>");
System.exit(1);
}
System.out.println("Host Address="+args[0]);
System.out.println("Port ="+args[1]);
ServerSocket ss = new ServerSocket();
ss.bind(new
InetSocketAddress(InetAddress.getByName(args[0]),
Integer.parseInt(args[1])));
System.out.println("ServerSocket Bound");
ss.accept();
}
}
I know this is not a Java/FreeBSD list, but I would be glad if somebody
knows a solution and would post it here.

No, I'm not using ARP, just a plain Tomcat installation.
