Julian Reschke commented on OAK-7182:
-------------------------------------
Current status:
- used baseline's (XML) output to identify exported APIs that reference Guava
- for these APIs (with one exception): (a) implemented Guava-free alternatives,
(b) deprecated the existing API, (c) added logging for all uses of the
deprecated API (currently at DEBUG, to be INFO in Oak 1.20.0)
- the exception are the cache API in oak-core-spi - this is way too dependant
on associated Guava APIs; for this: added DEBUG logging for all callers except
those currently in Oak; this logging to be bumped up to INFO 1.20.0 as well;
furthermore prepared for remoing it from the exported API in the future (which
IMHO will require embedding the classes in the three Oak consumers of the API)
The actual removal of the deprecated API would be an incompatible API change.
We might want to do it in sync with the API changes for Java 14 (see OAK-8561).
Once this is done, Oak modules could start using newer Guava versions by
shading them (potentially in a new Oak project that just repackages the shaded
Guava). Getting rid of Guava completely might even be better, but not realistic
right now.

> 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.
