I'm a teacher and I had prepared a BlueJ-project for my pupils. I copied this for everybody and they tried to open it with their computers.
How is it possible that a few computers opened the project incorrect? Sometimes the class' names have suddenly been written with lowercase letters (even though the original version didn't!) and though compiling was not possible any longer.
One of my pubils then changed capital/lowercase letters few times and tried to compile after every change. And suddenly it worked.
Has anybody ever heard about this problem?
