Even though Minecraft is not top quality code, you've provided very weak source. See [0] which provided memory usage analysis, that turn out pretty bad. It credits Notch (remember that he stopped working on the game at some point) as author of more optimal code, though ("The original Notch code (pre 1.3) was allocating about 10-20 MB/sec which was much more easy to control and optimize."). There are other problems with original Minecraft, that surfaced when people started to actively disassemble (or deobfuscate) it. But those are mostly unsourced, and I do not feel the authority to speak about it.
