 /**
  * Feature: Tests for Jabber plugin
+ * This test case is set to @Ignore because the Jabber Plugin is not able to connect to conference.localhost
+ * because DNS resolution issues. These issues arise because of the used Smack API
+ *      (http://www.igniterealtime.org/projects/smack/index.jsp)
+ * that does rely on successful DNS resolution, which is totally valid in terms on conformity with the XMPP Standard.
+ * 
+ * This test is broken until a new version of the jabber plugin with a new Smack Library is provided that falls back to
+ * using the hostname if the FQDN could not be resolved, *
+ *
