CancelledKeyException
---------------------
Key: ZOOKEEPER-106
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-106
Project: Zookeeper
Issue Type: Bug
Reporter: Flavio Paiva Junqueira
This exception seems to be harmless, but I thought it would be a good idea to
document it just in case I overlooked anything. I think it is harmless because
it is thrown inside the while loop that obtains the keys ready for I/O on
Factory.run(). The penalty is skipping all other keys available in the for loop
that follows the select call, but since we call again select in the next
interation, we don't miss much. An optimizatio, however, would be catching this
exception inside the for loop to avoid the extra call to select.
