[antlr-interest] Disabling overriden rule during iheritance.

[Martin Probst]

Hi,

The problem is most likely a token with the wrong id. ANTLR expects the
token that corresponds to the literal "header" (probably LITERAL_header
or sth similar) and get's a different token, that has the same text
("header") but a different ID. The error message is not very helpful - I
usually override it and provide the token number together with the text.

So the odds are indeed that you're lacking a "testLiterals=true" in some
identifier rule.
