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.
