Hi,
The following code is copied from
org.apache.ojb.odmg.locking.ReadCommittedStrategy:
/**
* release a lock on Object obj for Transaction tx.
* @param tx the transaction releasing the lock
* @param obj the Object to be unlocked
* @return true if successful, else false
*
*/
public boolean releaseLock(TransactionImpl tx, Object obj)
{
LockEntry writer = getWriter(obj);
if (writer != null && writer.isOwnedBy(tx))
{
removeWriter(writer);
return true;
}
if (hasReadLock(tx, obj))
{
removeReader(tx, obj);
return true;
}
return false;
}
Obviously, if there is a write-lock on an object, it will be removed
and then the method returns. If there are also read locks (and usually
there are!) they will remain active until the lock map cleans up those
'forgotten' locks. Bug or feature?
