Re: [eclipselink-dev] getLockMode()

[Darani Yallapragada <Darani.Yallapragada@xxxxxxx>]

Hello Guy,

I ran against the latest build and verified that LockModeType 'NONE' 
still registers in the 'getOptimisticReadLock' with the value false.

When 'lock( object, LockModeType.NONE)' method is executed , 
'forceUpdateToVersionField()' is called which makes the object with 
lockModeType 'NONE' to register

itself in 'getOptimisticReadLock()' method with value false. 

I can see the same pattern when I call find() and refresh() also.

Thank You

Darani
