Why doesn't hibernate.session.get(Entity.class, id) work when I change windows language from Chinese to English?

the code is like: Employee emp = (Employee) hSession.get(Employee.class, id);

It works well when windows language is Chinese.
but when I change windows language to English, it doesn’t work.
If I change back to Chinese, it works fine again.

If anybody has encountered the same situation and know how to fix it, please be kind to help me.

Thanks.
