Description of the solution adopted
Cache errors are usually handled by the cache client (that implements the JCache interface). However, in some cases the exceptions are thrown by the cache client itself (e.g. a timeout exception). Since we are agnostic w.r.t. the underlying JCache implementation, we cannot catch precise exceptions. Thus, this PR introduces a way to treat such exceptions properly, in a conservative way w.r.t. the data, and to log them via the logger and the metrics.

the pr looks good to me.
If you can just remove the 2 spaces in a couple of javadocs will be good
