Matrix calculation error

I get this error while calculating matrix

ors-app | 20 Feb 15:19:28 ERROR [errors.CommonResponseEntityExceptionHandler] - org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class

Am I doing something wrong? I have build the system for many datasets and it has worked, but now its not letting me calculate a matrix with a new dataset

The last release (v6.0) was a major upgrade. Did you remember to clean up all previous compiled targets etc? I.e. run a maven clean package before you ran it? Also the app.config was adjusted a little I think…

Thank you. Turns out I hadn’t updated to the new version. I will do that
