Here is the stacktrace. I have reproduced on 2.1.6

> Passing an Enum to Ibatis requires the declaration of a custom TypeHandler (see my comments here for my implementation: http://opensource2.atlassian.com/confluence/oss/display/IBATIS/How%20do%20I%20use%20a%20Custom%20Type%20Handler%20with%20complex%20property%20or%20Type%20Safe%20Enumeration)
> This works, except when the Enum is within a map or a list.
> That is, if I pass a list of Enum attributes to a statement, as a parameter, and attempt to iterate over them, they are mapped to UnknownTypeHandler. Similarly, when an Enum is passed as value in a HashMap as part of a parameter, it is also mapped to an UnknownTypeHandler.
