TDI 7.0 slow-starting assembly lines

When starting assembly lines from the config editor in TDI 7.0 it can often take 40s or more before anything happens.

The problem is that one of the XML libraries is trying to obtain a DTD (Document Type Definition) file from the Internet to validate a configuration file. The URL of the DTD includes the name of a long-dead website where even the DNS servers do not respond. As a result, we have to wait for the lookup to time out before anything happens.

One easy way to work around this problem is to add a line to the hosts file (e.g. /etc/hosts on Unix-like systems):

127.0.0.3 castor.exolab.org
