Re: [cross-project-issues-dev] core.jobs dependency on Java 8

["Thomas Watson" <tjwatson@xxxxxxxxxx>]

One thing to note is that Java 8 is already
supported for WebShere Application Server Liberty.  Also, the statement
of general direction from IBM is that IBM intends to support Java 8 for
WebSphere Application Server - Classic [1]

I would imagine by the time Neon is
released in June and used to build RAP applications most all the major
app servers should support Java 8.

Hi John,
today I found that another set of bundles that RAP uses from platform depends
now on Java 8:
org.eclipse.core.databinding
org.eclipse.core.databinding.property
org.eclipse.core.databinding.observable

Ivan

The fact that the Eclipse SDK as a whole
will require Java 8 doesn't imply that any particular bundle should require
Java 8. Since the change requiring Java 8 was cosmetic and there is a significant
impact caused by the change, I think it is fair to ask the question and
to consider the request. I have entered this bug for further discussion,
so please chime in there if you have an opinion:

One question for you Ralf, is whether this
is the only bundle RAP requires that is blocking you in this way? I thought
there were a number of other platform bundles already requiring Java 8
as well.

Hi Ralf,

Dani announced a while ago that Eclipse Neon will drop support for
Java 7. See: https://dev.eclipse.org/mhonarc/lists/cross-project-issues-dev/msg12177.html

Best regards, Lars
