Jess's boolean values are the atoms TRUE and FALSE. Don't use

instead use
isDetonation ? Funcall.TRUE : Funcall.FALSE);
"Boolean" values won't have any special meaning to Jess, and like any
other LISP variant, any value that isn't explicitly false is
considered true (so new Boolean(true) and new Boolean(false) are both
TRUE as far as Jess is concerned.)

Indeed. (not TRUE) is always false.
