Re: [eclipse-dev] NLS.bind(...) vs MessageFormat.format(...)

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

Hi,

An interesting thing with MessageFormat from JDK is that it's not part 
of "CDC Foundation 1.0" so e.g. JFace should not use it although it does 
(See https://bugs.eclipse.org/bugs/show_bug.cgi?id=209108)
