Mark Little commented on JBTM-2593:

OK, so for full details of why this really shouldn't have been a warning in the first place here goes ...

read_state takes a file type (ft in the parameters) ...

protected InputObjectState read_state (Uid objUid, String tName, int ft)

Within the method we get the current state of the instance ...

int state = currentState(objUid, tName);


All of these are valid values for the state to have (OS_UNKNOWN typically means "it's not there").

Assuming it's OS_COMMITTED or OS_UNCOMMITTED we're going to see if that's the state we expected when read_state was called, i.e., if ft is one of these. Then we do other "stuff"/

If the state isn't OS_COMMITTED or OS_UNCOMMITTED then we're not going to bother reading the state. If it's hidden (committed hidden or even uncommitted hidden) then we're going to return a null state and the caller interprets this at the higher level. For example, if it expected to find a state and got null back then it can call currentState and base its next actions on that value, e.g., then calling reveal_state and read_state once again. But the important thing is that just because the state is neither committed nor uncommitted does not mean that it's an error or a warning. That's for the caller to determine and not the ObjectStore implementation.
