Just get lucenes sources, change the line and recompile.
The difficult part is to get a copy of JavaCC 2 (3 won't do), but I
think
this can be found in the archives.

Sure. If \ isn't a token char, it end's the token.
So you will have to look for a different way of implementing the
analyzer. Shouldn't be that difficult since you have only one token.
Maybe it should be the job of the query parser to remove the escape
character
(would make more sense to me at least) but that would be another change
of the query parser...
