When there are no decorator defaults in root folder, causes stack trace in browser
----------------------------------------------------------------------------------

                 Key: JS2-942
                 URL: https://issues.apache.org/jira/browse/JS2-942
             Project: Jetspeed 2
          Issue Type: Bug
          Components: Decorations/Themes
    Affects Versions: 2.2-M1
            Reporter: David Sean Taylor
            Assignee: David Sean Taylor
             Fix For: 2.2-M1


During testing and usage, I suddenly started getting errors like:

java.lang.NullPointerException
	org.apache.jetspeed.util.Path.splitPath(Path.java:288)
	org.apache.jetspeed.util.Path.<init>(Path.java:100)
	org.apache.jetspeed.util.Path.addSegment(Path.java:339)
	org.apache.jetspeed.decoration.DecorationFactoryImpl.getLayoutDecorationBasePath(DecorationFactoryImpl.java:469)

I discovered that the PSML root folder.metadata had no default decorators. I am not sure if
I somehow I deleted this XML element with the customizer (I don't remember doing so), or if
its a bug in the system. I have never seen this bug in the 2.1.x branch, so I will keep an
eye out for it happening again. This work provided to fix this issue will:

* make the decorator factory defaults more robust, so that it can be configured to fallback
to a system-wide default if it fails to find defaults anywhere else (like in the desktop)
* configure a fatal exception handler in the Jetpeed Servlet so our end users do not have
to view a stack trace
