Are you on Windows? If so, please update Java to 7u21.
If on Mac, please only update to Java 6u45. Java 7 doesn't work with Mac.

Oh, in that case, his Java is about 30 versions out of date.

You should definitely update.

I've updated to the latest java however the .exe launcher doesn't seem to recognize my version even after re downloading the launcher from the website, ive also tried the .jar launcher which does realize im on the latest java but it gives me the following error:

Error: Could not create the Java Virtual Machine
Error: A fatal exception has occurred. Program will exit.

That has the link to the console log, it says

Error occured during the initialization of VM
Could not reserve enough space for object heap

but the .jar launcher wont let me add more than 1GB RAM

EDIT: Also the crash i mention in my first post occurs almost every time a visit a certain area and the only way to solve it (so far) is to have another player teleport me away from that location and i will be stable until revisiting that area.
