I forget at the moment, but isn't it necessary to construct some kind of 
java.io.XYZInputStream (or XYZReader) for the ANTLR parser? If so, it 
will generate the necessary end-of-file indication (even if the 
underlying byte or character source is not literally a file).

Perhaps what you're missing is the fact that EOF is built in to ANTLR, 
not something you define or supply. You simply use that built-in 
pseudo-token in your grammar productions where you want to require that 
the complete input has been consumed.
