Comment by Martin Ciglan [ 07/Nov/14 ]

Based on discussion & findings, casting is valid, issue should be resolved before that.

Finding:
Per specific model given, getKey() method within generated BuilderTemplate class returns returnType = Type (java.lang.String), which is a Java concrete type. Therefore, ClassCastException is thrown.

In progress...
