ValidateFalseReturnsHollow: Whether to return hollow objects (objects for which no state has been loaded) from calls to PersistenceManager.getObjectById(oid, false). This is the default behavior of Kodo 4.0 and above. Previous Kodo versions, however, always loaded the object from the datastore. Set this property to false to get the old behavior.

ValidateTrueChecksStore: Prior to Kodo 4.0, calling PersistenceManager.getObjectById(oid, true) always checked the datastore to be sure the given oid existed, even when the corresponding object was already cached. Kodo 4.0 and above does not check the datastore when the instance is already cached and loaded. Set this property to true to mimic previous behavior.

CopyObjectIds: Kodo versions prior to 3.0 always copied oid objects before returning them to you. This prevents possible errors resulting from you mutating the oid object by reference, but wasn't very efficient for the majority of users who don't modify oid instances. Thus Kodo 3.0 and higher does not copy oids by default. Set this property to true to force Kodo to copy.

CloseOnManagedCommit: If true, then the JDO PersistenceManager will close after a managed transaction commits, assuming you have invoked the close method. If this is set to false, then the PersistenceManager will not close. This means that objects passed to a processing tier in the same JVM will still be usable, as their owning PersistenceManager will still be open. This behavior is not in strict compliance with the JDO specification, but is convenient for applications that were coded against Kodo 2.x, which did not close the PersistenceManager in these situations. The default for this property is true, meaning that the PersistenceManager will close properly.

QuotedNumbersInQueries: Whether to interpret quoted numbers in query strings as numbers, as opposed to strings. Defaults to treating quoted numbers as strings. Set to true to treat quoted numbers as numbers instead to mimic the behavior of Kodo 3.1 and prior.

StrictIdentityValues: Whether to require identity values used for finding application identity instances to be of the exact right type. By default, Kodo allows stringified identity values, and performs conversions between numeric types.
