To provide further info, I looked at jboss log file server.log, after restarting it and running the console to get a process list.
I see a couple of errors:
2011-08-05 09:24:40,499 INFO [STDOUT] (http-localhost%2F127.0.0.1-8080-5) ERROR 05-08 09:24:40,495 (RepositoryServlet.java:doAuthorizedAction:78)
java.lang.NullPointerException
at java.io.OutputStream.write(OutputStream.java:58)
...
2011-08-05 09:24:40,587 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/drools-guvnor].[PackageDeploymentServlet]]
(http-localhost%2F127.0.0.1-8080-5) Servlet.service() for servlet PackageDeploymentServlet threw exception
java.lang.NullPointerException

...
But the funny point is that now, after an hour of attempts, a process appears both in drools-guvnor and the console !
But in drools-guvnor is my new Test process, while in console is Evaluation.
