I am using an interface, which declares constants, and I need to reference those in my code in this case

aFormGroup.setBounds(new Rectangle(A_CONSTANT,4,A_CONSTANT,5))

in JBuilder 9, this throws a nullPointerException

I'd like to know if there's a way to solve this, and why this did work in JBuilder 6.

thanks.

Run your program in the debugger,
and make sure that "aFormGroup"
isn't null.
