return null for class

reactor return null object when i use this code:

public UserModel getUserModel() {
return reactor.get("UserModel", new UserModel());
}

public void updateUserModel(UserModel value) {
reactor.put("UserModel", value);
}

Look at the reactor.get method implementation to understand why it returns null for a class. Check the key-value storage logic, possibly in the core database module. Test with the provided code snippet to reproduce the issue and see what 'done' looks like when the method returns a valid UserModel instance.
