Richard Downer commented on BROOKLYN-197:
-----------------------------------------
To reproduce: unplug your network cable and switch off wifi. Start Brooklyn. On
Brooklyn 0.8.0, it will launch normally; on Brooklyn 0.9.0-SNAPSHOT, the server
appears to start, but the web app is not deployed and the Brooklyn web port
reports 503 Service Unavailable.
Exception backtrace:

> Fails to launch unless Internet access is available
> ---------------------------------------------------
>
> Key: BROOKLYN-197
> URL: https://issues.apache.org/jira/browse/BROOKLYN-197
> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: Richard Downer
>
> Brooklyn 0.9.0-SNAPSHOT requires a connection to the public Internet to work.
> This is a regression from Brooklyn 0.8.0.
> This is an issue when Brooklyn is launched into secured server environments.
> It is common in many corporations that production servers have restricted
> egress access to the public Internet. Therefore this is a major issue.
> The issue appears to be that Jetty is using Xerces to parse XML files; Xerces
> is trying to resolve the DTDs by downloading them from the URL in the XML
> header. Therefore, it will be trying to access http://java.sun.com. When this
> operation fails, the root webapp is not deployed, and the Brooklyn web
> console (and probably the REST API too) returns 503 Service Unavailable.
