Description of problem: When command callback's onSucceeded or onFailed method throws an exception (like NullPointerException) and the callback has overridden shouldRepeatEndMethodsOnFail to return true, CommandCallbacksPoller keeps retrying the end method. This causes flooding in the logs for the failure to invoke the end method on the callback. Expected results: There should be a limit on the number of times CommandCallbacksPoller tries to execute the end method of the callback.
