It looks like that software tries to do some network access and fails.
This might be to due missing/wrong prox settings or too restrict
firewall or ...

Please use a network sniffer to find out whats wrong. I dont think it
has anything to do with a bug in SUNs JDK (I may be wrong) or a bug in
your Citrix sofware.
