Timeout exception when loading "Address Book" sample

Hi all,
I’m a newbie in Vaadin and Java.
And when loading “Address Book” tutorial I’m getting “java.net.SocketTimeoutException: Read timed out” error.
I’m using STS and Spring Source tc server, but the same error happens with Eclipse Helios and jboss 6.0.
In Helios it helps to set productionMode to true (probably it speeds up launching application), but with STS it had no effect, I have no idea why.
What can I do to avoid this error? Thanks a lot for any help.

PS: here is the stack trace:

Forum has helped: five minutes after creating a topic I’v found a solution - AdMuncher (though disabled) was an obstacle. Thanks for reading my messages. =)
