Could you attach a test case to a new JIRA issue demonstrating the problem? For better ease of use, I'd like to see a nicer error message instead of a GeneralException.

the embedded field can not be a mapped super class?

sorry about my bad english

i change that my embedded field to be a specialization class and works!
