Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Glad I found this. I see the exact same issue all the time in Windows with v1.7.4 in SSP. Thought it was a symptom of MC-162. Easy to reproduce here. Just entered game, got in my boat, rode, exited, lost access to it. Attaching dump.
In my work with EATS road (which started in 1.1) I had to deal with this bug quite often, There are many different ways this bug can appear and I made a video where I show the easier ones to replicate: http://www.youtube.com/watch?v=5_mcm4Zfh0A
I too have noticed this bug after 1.4.1 came out, and still persists in the 1.4.2pre released on the 24th october.
I discovered it in a different manner also, affecting boat floating mechanics somewhat because the boat elevator that i had was acting up. i've taken a few screenshots of a miniature experiment i did on the bug... Put simply, when a boat is placed on the iron block (first pic), a Ghost image of the boat sinks through the blocks and out of site, however the boat itself remains, you can tell, because when you move towards the iron block, the boats image reappears and the boat moves away.
Start
Placed
Sinks
Disappeared
Move closer
Reappears and moves away
The behavior i was expecting was that the boat would rise due to the water, or remain stationary on the block if a change has been made to prevent the floating behaviour.
Perhaps some sort of desync, looks like the sort of thing u would see in a multiplayer server where the server isn't agreeing with the client.
I'm running Java version 1.7.1_07 64bit, have windows 7 64bit
Mojang,please solve this problem c:
Also when you get on a boat and then when you get off the boat breaks
Same Issue!!!
confirm!
I confirm this bug is still present in 13w04a. It looks like a desync problem, where the server thinks the boat is floating up but the client doesn't and no updates occur.
I did some testing in 13w04a. Definitely a desync between the client and server. I threw some items on the boat, which landed on top of the boat for a second or two, only to correctly sync with the server and end up on the ground where they would have had the boat not been there. Pictures show what I mean.
Still in the most recent version!
Not sure if this is another manifestation of the same bug but when in 1.7.4 SSP when I exit a boat it usually becomes inaccessible. I can no longer get in it, I can't break it. If I exit and return it returns to a different location. (I have an enclosed pier and it always returns in a random location in water about 20 blocks away.) EDIT: This is described exactly in
MC-44750Is this still a concern in the latest Minecraft version 14w21b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Had an interesting encounter that sheds light onto the problem. Unfortunately I was slain so I could not produce a crash file of the situation.
In short, the problem seems to be that at least from the moment of entering the boat on, the boat is not located where it's image and the point of view of the user suggest it to be.
Boats nearly always act weird for me, as descibed in
MC-44750. But I never had a fight before on the water. This time I was attacked by a zombie while paddling around. First I shot arrows, but from the moment they left my bow they seemed to disappear. Then suddenly I was target of the zombie's fist storm, although it seemed to be about ten-ish blocks away in front of me, and facing at an other direction.I tend to place my boats some blocks away when entering, because there is so much trouble near land. (Now I understand this seems to be because the boat is not where it seems to be, so it breaks because of flat water at it's true location). I would say the distance between me and the boat while entering was about the same as the distance of me in the boat and the invisible location at the encounter. Also the direction is corresponding: when entering the boat I had placed it in northern-to-east direction, when I was attacked, the true location (where the zombie attacked me) was in southern-to-west direction from the location the boat and my point of view seemed to be.
This happened with version 1.7.10.
Confirmed in 14w30c.
As far as I can tell this is just pure desynchronization between the server and client side of Minecraft (Differing code/calculations? Perhaps use StrictMath instead of Math?).
While playing on a 14w30c server, I noticed another interesting phenomenon; once in a while, the server updates the boat's position and velocity to the client, but the velocity seems to be way off (slower, in my case). This is best noticed when using waterways (as seen in this old video). Can provide a test world if needed.
Confirmed in 14w31a
Boats have been changed and in my experience are more stable; fixed in 1.9 snapshots?
Assuming fixed, probably regular desync.
