org.apache.xmlrpc.XmlRpcException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: null

    When making an XMLRPC call after that XWiki has just started, an exception is raised in com.xpn.xwiki.xmlrpc.XWikiReflectiveXmlRpcHandler due to a problem with main XWiki context initialization. Everything works fine if XMLRPC calls are done after having accessed XWiki through HTTP (e.g., by opening a browser and loading the main page). Here it is the complete stack trace of the exception: java.lang.NullPointerException at org.xwiki.context.DefaultExecution.getContext(DefaultExecution.java:50) at
