Exception when open office server is not started should be more explicative

When trying to use the office viewer macro, for example, and the open office server is not started in the configuration of the wiki (Administration -> OpenOffice server), there is an exception on executing the macro, which is not explicative enough (see the exception under). Namely, the problem is that nowhere in the exception / stack trace is mentioned that the open office server is not connected and that starting it would solve the problem. It would be really helpful.

org.xwiki.rendering.macro.MacroExecutionException: Failed to view office attachment.
