Answer by Martin:
------------------------------------------------------------
It would be very nice to kick this module out of the Geotools code base.
However, it would requires volunter work. I took this script form the Mojo
project and modified it at a time when the Mojo's Jacacc plugin wasn't working.
Now the real Mojo javacc plugin is released:

    http://mojo.codehaus.org/javacc-maven-plugin/

We should delete our custom "maven/gt2-jjtree-javacc" plugin and use "javacc-maven-plugin"
instead. The two goals "javacc:jjtree" and "javacc:javacc" will be required (we need to
perform "jjtree" on the "module/main/src/org/geotools/filter/parser/expr.jjt" file first,
and then "javacc" on its output, taking in account the "module/main/modified-src" directory).
This Work is required because the "javacc-maven-plugin" is not working exactly in the same
way than the custom "maven/gt2-jjtree-javacc" plugin I did 10 months ago.

Note: "javacc" is used for generating a Filter parser. This code was setup by James and
Ian Schneider (if my memory serve me right) two years ago. I don't know if it still used
(which code people uses for filter parsing today?). The generated sources are there:

    http://javadoc.geotools.fr/snapshot/org/geotools/filter/parser/package-summary.html

This job may be easier to do after we fixed http://jira.codehaus.org/browse/GEOT-887
since it would make the "javacc-maven-plugin" easier to configure. In the main time,
since the "maven/gt2-jjtree-javacc" plugin is only used for the build and is not part
of the Geotools distribution, I guess that Geotools users don't need to care about this
Apache license.
