Persistence Extension Not Loading YAML File
Hello everyone!
I started using arquillian a few week ago and find it a very interesting and powerful integration testing tool.
But it seems that there is some kind of problem with the YAML files because it works When I use XML.
I am using Maven, Glassfish 3.1.2 and MySQL.
Right now I am trying to use the Arquillian Persistence Extension to populate my DataBase using the YAML file format.
But I am getting this Exception saying that it is impossible to cast a List to a String.
But where is the List !?
Here is the Exception:
------------- Standard Output ---------------
