proactive.useIPaddress does not work as expected

According to ProActive user manual, if proactive.useIPaddress if set to true, IP adresses will be used instead of machines names.
I try to run the nbody example on a system with two network interfaces - an ethernet interface and a wlan interface - cortex pour les connaisseurs ;) I monitor the network traffic on the wlan interface using (link: my favourite TCP monitoring tool). Even though I set proactive.useIPaddress, the tool reports DNS lookups that are being done:

22.680268 (link: dns_server_ip_addr)0 -> (link: ip_addr) DNS Standard query response A (link: cortex_ip_addr)

(link: dns_server_ip_addr), (link: cortex_ip_addr) and (link: ip_addr) are placeholders for IP addresses.
The problem gets serious if I also use proactive.hostname to specify a certain IP address for ProActive to use. In this case, the value specified for proactive.hostname will sometimes be used, and sometimes not.
