[eclipse-pmc] Deprecation of MessageXxx classes

[Dirk Fauth <dirk.fauth@xxxxxxxxx>]

Dear PMC,

some years ago I introduced the following three interfaces:

MessageConsumer

MessageSupplier

MessageFunction

It was because a dependency to Java 8 was not yet available for the Eclipse Runtime. The idea was always to replace those interfaces with the java.util.function interfaces. But with publishing the org.eclipse.e4.core.services.nls package as API the change was not that easy anymore. And I forgot about it to be honest.

To clean up I would like to remove those interfaces and replace them with default interfaces. The related bug is https://bugs.eclipse.org/bugs/show_bug.cgi?id=512665

I therefore request for removal of those interfaces.

Greez,

Dirk
