Re: [cross-project-issues-dev] Has Java 5 Platform support been discontinued?
|
I seem to have a knack for definitive statements
lately so I'll take a try at this. The last Eclipse Platform release to
officially support Java 5 was 3.6/Helios. We have not run our tests against
Java 5 for several years and can make no claim that it works. Since Platform
3.8 it has certainly been impossible to run the complete platform using
Java 5 due to Jetty dependency on Java 6 (and possibly other bundles).
Oracle Java end of life was in 2009 (in fact Oracle Java 6 is also past
end of life now). Some individual bundles may still support older runtimes
but at this point they are the exception rather than the norm. The list
of bundle EE levels is updated with each plan revision, but as long as
they are within the scope of the current list of reference platforms they
are not generally announced individually.

Hi
I am doing my best to continue support for existing functionality, so in
the absence of a clear Eclipse statement that Java 5 support is terminated,
I feel I have to continue to keep close to 5.
Guava changing to Java 6 was awkward.
OSGI changing to Java 6 is very close to a mandatory downstream consequence.
Can we please have a clear policy statement rather than a secretive creep.
I don't mind changing to Java 6, it probably makes life easier. But I hate
this are we 5 or 6 limbo?

https://bugs.eclipse.org/bugs/show_bug.cgi?id=411419
I am not sure if this is related to the issue you are seeing ... or if
merely confirms yet another "unannounced change" ... but I don't
think it changes the bottom line:
If you want things different than they are, open a bug or comment on an
existing one. If it is merely a matter that you don't really care, but
you have to change your test scripts, then all I can say is "sorry".

Hi Szymon
Your list omits the 'culprit'.
It is org.eclipse.osgi.util.NLS that is now Java 6 putting paid to all
attempts at internationalization with Java 5.
