Bugs and Issues: Java, Memory "Leak", Performance and Snake

Issues:
1(Bug). After the game is closed, the memory is not freed. I will provide a screenshot lower.
2. Does the game really have to use Java?(I understand, an entire game was written in Java, you can't change that but may be there is some way?).
2.a. I had to install Java and I have very serious concerns about security... We all know that Java has A LOT of serious security problems/leaks.
2.b. The performance is awful.
2.b.a. My powerful quad core i7 and nVidia GT 540M can't handle it very well. The laptop is heating harder than it is heating when I play GTA 4, I have the feeling that the game will melt the plastic grid I have to the side(It happened to my brother)...
2.b.b. If I activate the shadow or antialiasing in game, the game starts lagging hardly. And this laptop can handle on Max settings almost all the new games...
3. Java eats all my RAM, it's unbelievable how much RAM it uses. In order to play the game you need a beast of a computer.
Here is a screenshot:
As you can see, the game is eating ~1.2+ GB. After you close it, javaw still runs and it is eating ~700 MB.
Bugs:
1. A snake bit me, I ran away(climbed a wall and was able to run freely). I recharged my health, everything was to full. The poison of the snake was still on me. When the snake was to far away the battle mode deactivated and at the same moment my guy fell on the floor stunned... Then as the help hint says, I was sent to my "home" location and dropped all the items. But this shouldn't happen, it says there that if one of my Humour goes to 0 than you get stunned while I had all to full...
Edit: I've read from wiki "You have been poisoned by a Timber Rattler. The effect of the venom will drain your Phlegm, and inevitably knock you out, unless you can administer Rattler Serum in time." so this is not a bug.
