activiti-webapp-rest2 exception

[hbacanak]

I have downloaded and made some modifications activiti-webapp-rest2. Modifications are changind the database to postgresql and moving build automation mechanism to gradle. No changes are made to spring configuration. Application is working without problem, responding rest service calls. Yet in debug mode following exceptions is generated continously without any http request. At  info level no exception is shown. Anything comes to mind to prevent the exceptions? Any timed tasks trying to access secured services that needs to be configured?

please ignore this, gradle is running application just fine. I guess it is an ide specific problem.
