Upon changing my name with the new profile name changing feature, and then logging onto a server, I discovered that not only was I where I had logged off yesterday, but my inventory had the same items in it.
The world, though, was still altered by the changes I have made earlier today, meaning that the items I put into a chest were still there, allowing me to now have two fortune pickaxes.
Detailed explanation: I logged off yesterday in a specific spot in my branch mine. This morning, I logged back on and continued to mine ores and put them into chests. As soon as I got aware of the new name changing feature, I logged off, changed my name, and logged back in.
I was now at the exact spot I had logged off yesterday, even my inventory was the same. The ores and pickaxes I had put in the chest were still there, allowing for a new kind of duplication glitch - even though it only works every 30 days.
It should be said that my connection to the server isn't the best, so that might just play a role. It is also very unlikely that it has something to do with the owner deleting/altering my server profile file, as he is offline ATM. Best guess I have that it has to do with the name change.
Just to be clear, I can use everything in my inventory and in the chest, so the duplication does not create ghost items.
EDIT: Just discovered that this keeps happening every time I log onto any server, even without Optifine installed.

I doubt that Optifine has anything to do with this. It does not modify the game itself, or the connection to a server.
Of course I cannot be sure that this also works without Optifine, it would have to be tested out. I myself can't really do that because of the 30-day period in which you cannot change your name. I just did discover some interesting behavious: This bug keeps occurring whenever I relog onto the server. Even did this without Optifine, and it keeps happening ... interesting enough? Also tried it on another server, where I spawned where I logged off a few days ago. Have played on there, since.
Is this still an issue in the current Minecraft Snapshot 15w47c or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Invalid as it relates to a modified client.
