I can move it to another enum. But we need at least one instance something like
(limitation of enum)
public enum VdcParameter implements IVdcParameter {
Unknown(Void.class);
....
}
More over enums cannot extend other classes or other enums, they can only
implement Interfaces. So every enum should have the methods
@Override
public Class getJavaType() {
return javaType;
}
@Override
public String getKey() {
return this.name();
}
@Override
public String toString() {
return VdcParameter.class.getName() + "." + super.toString();
}

I had to add this for Json serialization/desrialization
The recommended way of serializing in Jackson is Collection<VdcParameterValue>
rather than Map<String, Object>. Serializing/Deserialzing does not work with Map
When we deserialize we rebuild Map<String, VdcParameterValue> from
Collection<VdcParameterValue>. So we need the key(IVdcParameter) and
value(Object) to rebuild the map.
If need VdcParameterValue class to support the use case of Json serialization
and deserialization.

Line 8: private IVdcParameter key;

Will do
