ZOOKEEPER-2809: Unnecessary stack-trace in server when the client dis⦠Unnecessary stack-trace in server when the client disconnects unexpectedly. Backport from master, branch-3.5 to branch-3.4. Removes unnecessary stack traces from the catch blocks of method doIO in NIOServerCnxn. For EndOfStreamException stack trace is replaced with logging only the message and also contains the removal of stack traces for exceptions CancelledKeyException and IOException as per commit 6206b495 referenced in the ticket. This change is necessary as there are projects which consider all stack traces as bugs. For CancelledKeyException and IOException developers are still able to see stack traces at log level Debug. This change is in sync with master and branch-3.5.
