I can't think of any way to be clearer than I already have. The platform
requires Java 6, and it has required Java 6 for several years. Next time I do a
plan update I will try to make that even clearer.

Hi
I'm sorry John but you are dodging the issue. There is far too much this is
what we do, and very little of this is what we require.
/Most of the Eclipse SDK is "pure" Java code and has no direct dependence on
the underlying operating system. The chief dependence is therefore on the Java Platform
itself. Portions are targeted to specific classes of operating environments, requiring
their source code to only reference facilities available in particular class libraries
(e.g. J2ME Foundation 1.1, J2SE 1.4, Java 5, etc)./
/In general, the 4.3 release of the Eclipse Project is developed on a mix of
Java SE 6 and Java SE 7 VMs. As such, the Eclipse SDK as a whole is targeted at
all modern, desktop Java VMs. Most functionality is available for Java SE 6
level development everywhere, and extended development capabilities are made
available on the VMs that support them./
Yes there have been a few bundles that needed 1.6 for some time, but it seems
like the critical parts of the platform have been 1.5. The list on
_http://www.eclipse.org/projects/project-plan.php?projectid=eclipse#appendix_
still shows very little that needs 1.6, so I see no statement that the platform
needs 1.6.
I delivered my Indigo, Juno and Kepler releases as Java 5 minimum requirement.
Clearly the platform and many projects were highly Java 5 tolerant.
There should perhaps be a separate overall statement at the top that 1.6 is the
minimum requirement (although some bundles may be more tolerant).
Or org.eclipse.core.* needs to change to 1.6

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?

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.
