Maurice Amsellem commented on FLEX-33865:
-----------------------------------------
Benoit,
That's something else, and it could probably be easily fixed by modifying the
regexp (JIRA?)
I think that if the initial coders of this function used that complex regexp
processing instead of the obvious indexOf(":"), they probably had a good reason
for that, or maybe it's just over-engineering.
Unfortunately, I don't know the history of that code, so I cannot accept a
change that breaks the current design without discussing it with the team.
I will post the discussion on the dev list and will let you know.
