LockMode hash differs in x86 and 64bit OS
-----------------------------------------
Key: NH-2755
URL: http://216.121.112.228/browse/NH-2755
Project: NHibernate
Issue Type: Bug
Components: Core
Affects Versions: 3.2.0Beta2
Reporter: Anton
Priority: Major
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)

---------------------------------
What you are doing is pass the NH's LockMode serializaed instance between 2 different machines, right ?

---------------------------
Yes, LockMode just passes from client to server PC, client is x86, server is 64bit.
When using client 64bit and server 64bit - everything ok.
Stored hashcode in instance of LockMode differs at 86/64

---------------------------------
Well... that is not the only one place where NH store the hash code at ctor.
