[Umberto Nicoletti]

This is probably not related only to java mapscript, so please read on.

Could someone of the other mapserver developers shed some light on this issue?

I have a clue to give: php mapscript is using a different regex
library and this explains why the match does not happen for Java
mapscript, while it does happen in php mapscript. If I am right also
the mapserver cgi should be affected and possibly all other mapscript
too.

It would be very interesting if someone could report on similar
experiences with the cgi-bin version of mapserver.

Thanks,
Umberto
