wrong door, jek jek tar, is not a room in the docks, it's a different zone, if you come from the ebon hawk, walk towards the hutt, then take a right just before his room, go up there, should be an entrance you walk into, and zone into another zone, thats the bar...
the doors that can't be opened, could be placeholders for things they didn't implement, side quests spots (you notice when you zone into different places with apparently no entrances etc?).
this game is very buggy indeed, but this one is not one of them.
