Hello,
I've run into an incredibly annoying issue. I have an entity class ParameterSet, that is associated with a Collection of entity Parameter classes. The Parameter class is made up of simple value type attributes and two type safe enumerations. One of the type safe enumerations is called ValueType (code below). The method nullSafeGet(ResultSet resultSet, String[] values, Object owner) throws a NullPointerException under 3.1-RC1 because the ResultSet returns null. This attribute was marked with a multiplicity of 0...1, and is allowed to be null in the DB, so it seems like this should not be throwing a NullPointerException, when that Enumeration attribute is allowed to be null.
