as said before. we need someone that can fix the custom lexer to be able to handle the whitespace at the end of the file. for the rest a regeneration should work.

Note: I wonder if there should be replaceAll ...

In general the whitespace handling has to be fixed.
the positions in the real file and in the lexer have to match.

you can have a look at my fork to see what i have done so far.
i cannot verify if my work did any damage to the correctness of the parser
nor that it solves the problem in all cases.
