Instead of using 'java.util.List', what if using a special List, e.g., 'scala.collection.immutable.List'

[Myoungkyu Song]

Hello,

I would like to ask about the one-to-many relationship in JDO. The
below code is a actual working code.
Instead of using 'java.util.List', what if I use a special List, for
example 'scala.collection.immutable.List'
as a collection? As my test, jpox enhancer said, "..has been defined
with "collection" MetaData yet is not a Collection Field."

Best regards,
Myoungkyu
