Normally ANTLR will try to continue regardless, though it depends 
on how your grammar is structured and which version of ANTLR 
you're using.

@header { foo } is just shorthand for @parser::header { foo }, 
when used in a combined grammar.

It's better to explicitly use @parser::header { foo } and 
@lexer::header { bar }.
