[antlr-interest] Post CommonTokenStream in the parser constructor

[Luke Silver]

OK, I managed it. IŽve only inserted a new constructor in my parser:

public MyParser(MyLexer lexer) {
super(new CommonTokenStream(lexer));
}

And now the following parser call works:

MyLexer lexer = new MyLexer(input);
MyParser parser = new MyParser(lexer);
