RapidMiner Server not starting up any more

I run RapidMiner server on an CentOS server and I am all of a sudden no longer able to restart it using the standalone.sh script.  

The script goes through the first few steps until it gets "ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC00001: Failed to start service jboss.serverManagement.controller.management.http: org.jboss.msc.service.StartException in service jboss.serverManagement.controller.management.http: java.io.IOException: Unable to load resource handler", which it always has.  

But then instead of continuing with "INFO [org.jboss.web] (ServerService Thread Pool -- 54) JBAS018210: Register web context:" and "INFO [org.jboss.as.server.deployment] (MSC service thread 1-26) JBAS015876: Starting deployment of "null" (runtime-name: "rapidminer-server-war-reporting.war")" and so on as it used to, it now skips all this and shows immediately after the exception "INFO  [org.jboss.as.controller] (Controller Boot Thread) JBAS014774: Service status report JBAS014777: Services which failed to start: service jboss.serverManagement.controller.management.http: org.jboss.msc.service.StartException in service jboss.serverManagement.controller.management.http: java.io.IOException: Unable to load resource handler".

Here's a pastebin of the currently failing startup http://pastebin.com/Nrn4nUL6 and here is one from a previous successful startup http://pastebin.com/my5cCLy5.

Any idea what could be causing this?
