I can not comment on the source code change but I am using the
command above to generate a .tex and .ps file:

  java -cp ../tla2tools/tla2tools_1.8.0.jar tla2tex.TLA \
     -shade -number file.tla

This generates line numbers and I am then using the .tex file for
further processing.

If you prefer using tla2tex.TeX:  I also tested embedding the TLA+
specification within a `linenumbers' (LaTeX package: lineno)
block and this generates linenumbers as well:

--8<---------------cut here---------------start------------->8---
\usepackage{lineno}           %%% use lineno package to generate line numbers
\nolinenumbers                %%% by default, turn line numbering off.

Some explanation on \texttt{GCD}:

-------------------------------- MODULE GCD --------------------------------
EXTENDS Integers
Divides(p, n) == \E q \in Int : n = q * p
DivisorsOf(n) == {p \in Int : Divides(p, n)}

SetMax(S) == CHOOSE i \in S : \A j \in S : i >= j

GCD(m, n) == SetMax(DivisorsOf(m) \cap DivisorsOf(n))  \* gcd of $m$ and $n$
SetGCD(T) == SetMax({d \in Int : \A t \in T : Divides(d, t)})

Followup text without line numbering.
--8<---------------cut here---------------end--------------->8---

Commands to generate a PDF file:

  java -cp tla+/tla2tools/tla2tools_1.8.0.jar tla2tex.TeX doc.tex
  pdflatex doc.tex

Hope that helps,
