I know, bad form to reply to my own post, but ...
After a few discussions on comp.emacs.xemacs, I found out that etags is
still under active development, maintained by Francesco Potort�.
Thus I'm going to rollback my changes once I can get my hands on the
latest etags.
However, there are significant problems with etags in JDE that I am
wondering about, for instance, the problem with static methods. Has
anyone else experienced these problems with tags in JDE?
Best,
Stuart
