[antlr-interest] Why does this conflict?

I thank you for calling attention to the difference between parser
literals and lexer tokens. It is a nice way to eliminate many annoying
non-determinism warnings when looking for both keywords and identifiers.
But there is a gotya which I was lucky enough to catch in one of my test
cases. In my lexer, I strip the quotes from strings since I don't need
them in my tree (and also don't want them in my output). Unfortunately
that makes them candidates for reinterpretation.
Solution, override testLiteralsTable in the lexer
public int testLiteralsTable(int ttype)
if (ttype == PreprocessorParserTokenTypes.STRING)
