Re: [modeling-pmc] Guava/Guice update and version bump
I would try to allow Java 11 without killing all existing Xtext languages. 
I cannot tell whether that is possible, though.

so you would rather never support java 11 than releasing a Xtext 3.0
or would you simply bump the dependencies, try to use guava 24-21 api only and dont care about manifest compatibility?

how does that fit with orbits policy to delete stuff?

Because of the huge impact with bumping the major version, we never do that, even if we can't avoid breaking a couple of clients.
It is just better to break a hand full of clients than stopping everyone from updating to the latest version.
There is no general answer, it always depends on whether the benefits of such an upgrade carry the downsides (breaking).
Bumping the major version has such bad downsides that I'd consider it never being a good idea.

The main problem is:

what if e.g. java 11 requires to update these libaries?
how did you handle that is the past?
(https://dev.eclipse.org/ipzilla/show_bug.cgi?id=5816)
which was done in Nov. 2011 which was likely Xtext 2.1 or 2.2
=> no major version bump

=> i'am totally unsure what binary compatibility means regardings
dependencies / manifests (we have other things that break e.g. through
orbit changes

Thanks
