Sealed hierarchy of case classes serialization won't work

Sealed hierarchy of case classes are widely used in Scala, however in Jackson-Scala they don't seem to be supported.

We are looking for a workaround: when we try to add custom serializers / deserializers for our sealed trait and then use the default "serializers" for the subclasses, the serializers/deserializers for the trait take higher priority and this results in a Stackoverflow error.

Is there a solution for this?
