there are 22 Times: Catching exceptions with empty bodies.

> There are exceptions of different types: InterruptedException, KeeperException, Exception,
etc.. Even though we think that these exceptions should never occur, if they are captured
it means that they are technically possible. In case that they do happen, it will be very
difficult to know what is happening and to diagnose the problem. It is very recommendable,
at least to add a log trace, in case these exceptions are triggered.
