>             Project: Hibernate Core
>          Issue Type: Bug
>    Affects Versions: 3.3.2
>         Environment: Hibernate Core 3.3.2, problem is independent from database type (actually appeared with Derby 10.4.2)

> POJO Entity with 100% JPA annotations, as long as the Class did not implement the Map interface everything worked fine (save to and load from database).
> After the Class implemented the Map interface, during object persistence,  'get' was called with '$type$' parameter, and 'get' responded with IllegalArgumentException (in accordance to its design).
> Workaround implemented: get now responds to this call by returning getClass().getName()
> BUT Hibernate should not need this workaround if it is 100% JPA compliant.
> On the above example the Map interface of the Entity Class had no connection with persisted variables, only transients.
> In the JPA spec there is no restriction what I know of, which would disallow the implementation of Map by an Entity Class.
> In the JPA spec there is no requirement what I know of, which would require and Entity Class which implement the Map interface to implement the Map interface in any special way (like 'get' responding to '$type$').
> Correct me if I am wrong.
