>          Issue Type: Bug
>          Components: Core

> When using LockMode over remoting between PCs with x86 and 64bit operating systems there is different result in GetHashCode.
> It leads to error "LockMode Upgrade not supported by NHibernate.Persister.Entity.SingleTableEntityPersister " when I pass LockMode.Upgrade from x86 to 64bit to do
> session.Lock(this, lockMode)
> It is caused by generating and storing hash code upon creating instance of LockMode.
> LockMode constructor uses a XOR (^) operand to generate and store hash code, and it has different behavior depends on OS type (x84, 64bit)
