I was cutting myself today due to this bug and it occured to be Java related issue rather than my coding.
Example is very simple - always add 1 to angle. Always set counters to X and Y of Action Point (which is in bottom of the Line).
In windows and MMF iit makes a nice circle and both counters change. in Java it shows only initial value.
I need it to be working by this Wednesday due to being part of my coursework - is it possible?
