I have an
class B forward reference of base class A
error (at compilation)

obvious class B has "import A"

this is while compiling a third class C that has
import A
import B
C is on a different package.

Anybody knows what's going on?

thanks
(I had solved this yesterday by changing the imports and/or compilation order,
but because of a user error (me) I had to restore older backups
and now I'm stuck)
