I see in your archive that you have ExprLexer.java, etc., generated
with ANTLR 3.1.2, and ExprLexer2.java, etc., generated with ANTLR 3.2.

I did a diff between my generated 3.2 with your 3.2 and they are
identical except for the first lines that have the version and
generation time stamp.

As for your generated 3.1.2 and my generated 3.1.2, there are some
differences, but structurally they look largely the same, and when I
plugged your 3.1.2 Java sources where my 3.1.2 would go, the resulting
code worked fine, just like my own 3.1.2 did.

I am not sure what your question is.
