IIRC, the problem is that arrays rely on "[]" which are part of the
ANTLR grammar and that this is falsely attributed to be a parameter for
a rule. As far as I know there is no way to prevent this behaviour right
now. A workaround would be to declare flqs as object and cast it in Java
to a String array.
