Circuit Breaker load balancer is a stateful pattern that monitors all calls for
certain exceptions. Initially the Circuit Breaker is in closed state and passes
all messages. If the are failures and the threshold is reached, it moves to
open state and rejects all calls until halfOpenAfter timeout is reached. After
this timeout is reached, if there is a new call, it will be passed and if the
result is success the Circuit Breaker will move closed state, or to open state
if there was an error.</p><p>An example using Java DSL:</p><div class="code
