In GNU Classpath this comes from
tools/resource/gnu/classpath/tools/gjdoc/version.properties.in
Which is just one line:
gjdoc.version=@VERSION@

The idea is fine. But then please do also submit a patch to GNU
Classpath that just removes the whole getGjdocVersion() method.
Note that there is another variant called getDocletVersion() in
HtmlDoclet.java that you also want to change in this case.
