The problem was IPv6 policy set to drop and no any additional rules added, even loopback pass-through (though, IPv4 configured to accept all lo<->lo traffic). But for some reason tomcat wants IPv6 connection and while time (retries * timeout) passed - it hangs at start. And I even don't know - what subsystem use such kind of interconnection (via IPv6 loopback).
