Groovy 2.0.1, GroovyCastException on my own class?

Question

I'm extensively using groovy classes in my web app project. I can create an instance of a type (defined as a groovy class) but can never at a later time cast back to it (GroovyCastException occurs).

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.company.role.delegation.ProfileModel@49ee6848' with class 'com.company.role.delegation.ProfileModel' to class 'com.company.role.delegation.ProfileModel'

According to the above error message, the source and destination class types are the same. Huh?

Answer 1

Most likely the reason is that the class have been loaded twice via different classloaders. Check if the getClass().getClassLoader() for both the instances are identical.
