Subject Re: [Exception]Key expressions are only supported on POJO types and Tuples
Date Wed, 11 Feb 2015 08:59:16 GMT

you are right, there is a problem. I reproduced the problem and it seems
that regular Scala classes are not properly analyzed and not identified as
As long as you only need these classes to be data holders without custom
logic, you could go with case classes.

I will open a JIRA to extend Pojo support for regular Scala classes.

Thanks for reporting,
