@arkadius I am not familiar with caffeine but it looks promising. A quick
glance through the LICENSE indicates that it is compatible and has only a
single dependency on Google Guava, which is also compatible.
I would avoid updating the other references blindly, though. We would need
to do some evaluation to see where it does and does not make sense. Especially
if used in a context where thread safety is not required.
