Its not actually at all relevant in the test that Hibernate is generating the schema. In fact here is the schema Hibernate generates in my test which you would have seen if you run the test:

    create table Entity1 (
        id integer not null,
        name varchar(255),
        theDate bigint,
        primary key (id)
    )

As you can see, the test is using a numeric column physically in the database too.

So at this point I'm likely to close this as I am not able to reproduce it. As I suggested to Courtney on HHH-8842 try building Hibernate from source (HEAD of 4.3 branch) and see if that resolves your problems. That, or I am going to need a test case that can reproduce the failure you see.
