Possibility of dropping Forgerock/Guava in favor of Google/Guava

[krystofNovotny]

The current version of Forgerock/Guava is old and no longer developed.

This issue is about exploring the possibility of replacing Forgerock/Guava with the latest version of Google/Guava and specifying problems it would create.

I'm looking for answers to those questions:

• Is it feasible?
• What changes would have to be done?

I think we know answer to those questions thanks to our latest tinkering with Wren:IDM dependencies... It is better to have shaded Guava because a lot of other libraries depend on a different version which makes it jar hell situation. Feels safer to have our own version locked in.
