Alex Deparvu commented on OAK-7182:
-----------------------------------

bq. or to use reflection to support old and new Guava?
I went ahead and added a prototype of this based on the latest patch [0], just 
to see how crazy it would look.
I ended up with 2 classes wrapping the guava apis. The executor stuff is still 
ok [1], but the toStringHelper is pretty weird [2], we have to remap the entire 
api footprint, it would be easier to rewrite it (or just copy the code over).

I hope this gets the discussion moving again, I would love to see this resolved 
in some way.

> We currently rely on Guava 15, and this affects all users of Oak because they 
> essentially need to use the same version.
> This is an overall issue to investigate what would need to be done in Oak in 
> order to make updates possible.
