[eclipselink-users] Postgres arrays

[Mike Traum <Mike.Traum@xxxxxxxx>]

Hi,
I'm trying to get a mapping for postgres arrays working. I'm using a 
Converter and thus far (without a lot of testing), inserting an array 
seems to work fine. But, when reading that array, eclipselink (1.2) 
throws the following exception before we even get to the Converter:
java.lang.ClassCastException: [D cannot be cast to [Ljava.lang.Object;
   at 
org.eclipse.persistence.mappings.structures.ObjectRelationalDataTypeDescriptor.buildArrayObjectFromArray(ObjectRelationalDataTypeDescriptor.java:326)
...

The problem seems to be that eclipselink is attempting to cast 
java.sql.Array.getArray() to Object[], but postgres returns an array of 
primitives. This seems like an eclipselink bug, no? Any idea for a 
workaround?

Thanks,
Mike
