Description

Using oidc-client.js and a redirection url of "http://localhost/". After login the "monitor" will attempt a request every second using the InAppBrowser instance that was logged in with.

Occasionally, this will result in the following null pointer exception.
java.lang.NullPointerException: Attempt to invoke virtual method 'void org.apache.cordova.CallbackContext.sendPluginResult(org.apache.cordova.PluginResult)' on a null object reference
