Cannot kill the process javaw.exe from Minecraft

javakillminecraftprocess

I start up Minecraft, close it using Quit game or press the close button and the window closes but not the javaw.exe process and when I try to kill it in the Task manager nothing happens. When I try to kill it in Process Explorer nothing happens either, not even when killing the tree, suspending it first etc.

It's eating up all of my PC's memory and the process will only close when a reboot happens and won't close when logging out and in. I googled around and some people are having it too but they don't seem to be finding any solution.

This is a reported bug for Minecraft (reported officially today).

See bug MC-1408 "Javaw.exe keeps running after closing minecraft".
