Hi Chamila,
This culprit seems to be the following line in startServerExtension()
method of DefaultExtensionHandler
ExtensionUtils.executeStartServersExtension(Collections.<String,
String>emptyMap());
It is trying to add elements to the empty map created above
envParameters.put("STRATOS_APP_PATH",
CartridgeAgentConfiguration.getInstance().getAppPath());
