Title:
  X 1.0rc1 sikuli-script.jar not working on Linux Ubuntu 10.04 64bit

Status in Sikuli:
  New

Bug description:
  I need your help to figure-out if 'sikuli-script.jar' from 'Sikuli X
  1.0 RC1' package is supported for Java programs running on Linux
  64bit?

  What is that I'm attempting?
  Use Sikuli-X script within Java program (JVM 1.6).

  What's the problem?
  The problem I'm facing is the below mentioned Error dump. This error occurs when executing a simple Java program which attempts to call 'Screen.find("image.png")'.

  What's working?
  The good news is "./sikuli-ide.sh" works on my Linux Ubuntu 10.04 64bit. Hence, I can only execute sikuli scripts on my linux desktop from sikuli-ide.
