If this is deprecated (although I can see no evidence of it myself) then it
is a big mistake.
I suspect that it is not deprecated. I would recommend the following pattern
for numeric primary keys:
public class MyPK
{
int value;
MyPK() { ... }
// hashCode and equals ...
}
This is preferable to using java.lang.Integer as a primary key type as it gives
you better type safety (you can't accidentally pass an AccountKey where a
CustomerKey is expected).

We also permit entity components to have non-valuetype primary keys in our
product, but the mechanism is proprietary and so we leave it undocumented.
