The '$' get generated by compiling certain java classes (was it with inner
classes or something) anyway it's normal for java. I could suspect that
this file might be missing from the antlr.jar. You can check with:

jar tvf antlr.jar

If it's missing you can try following the build instructions to build the
jar file anew. On unix the configure+make recipe should work as well.

Cheers,

Ric
