My suspicions proved wrong - I disabled ipv6 by doing following:
cat >/etc/sysctl.d/40-noipv6.conf <<ENDOFIPV6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
net.ipv6.conf.eth1.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.vboxnet0.disable_ipv6 = 1
ENDOFIPV6

.. and after reboot, the javaws still spends many minutes until I get
the application's screen (if at all).

For what it worth, the application in question is IPMI as provided by
SuperMicro daughterboards.

Title:
  openjdk takes long time to download an JavaWS application

Status in “openjdk-6” package in Ubuntu:
  New

Bug description:
  I am trying to open an JavaWS application, the jar download window
  appears (see attached) but it takes long time (several minutes) to
  download the jar file.

  Could be the problem is related that openjdk initially opens the
  connection over tcp6 and then falls back to tcp4?

  I have no tcp6 in the network, no idea why it thinks I have it.

  Configuration: ubuntu 11.10 (oneiric), openjdk-6-jre
  6b23~pre11-0ubuntu1.11.10, icedtea-netx 1.1.3-1ubuntu1.1.

  # netstat -anp | grep java
  tcp6   70962      0 10.66.88.26:57103       10.0.3.81:443           ESTABLISHED 18968/java
