New question #245672 on Sikuli:
https://answers.launchpad.net/sikuli/+question/245672

Hi, all.

I write some sikuli script in jython. And it works OK under Eclipse. But when I compile the jython script to *.class, and run it on command line, a NullPointerException raises.

Environment: win7 64, sikilu 1.0.1

Run: java -cp jython-standalone-2.7-b1.jar;sikuli-java.jar;. myapp$py

Error:
