Potential NullPointerException in ServicesServlet.writeJSON()
-------------------------------------------------------------

                 Key: FELIX-2260
                 URL: https://issues.apache.org/jira/browse/FELIX-2260
             Project: Felix
          Issue Type: Bug
    Affects Versions: webconsole-3.0.0
            Reporter: Felix Meschberger
             Fix For: webconsole-3.0.2


The ServicesServlet.writeJSON() method calls the ServicesServlet.getServices() 
method and does not expect this method to return null. Yet, if no services are 
registered (which is highly unlikely) null might be returned. The writeJSON() 
and getStatusLine() methods should be secured against this potential 
NullPointerException.
