Title:
  While playing Minecraft, CPU usage skyrockets

Status in “openjdk-7” package in Ubuntu:
  New

Bug description:
  Tried this from a Live USB with Fglrx (persistance).

  When playing Minecraft, I noticed major lag spikes. Upon checking top,
  I found that Minecraft consistently uses at least 130% in CPU
  resources. I have a 6 core PC, so this is pretty crazy.

  Does this without fail every time the game is launched.
