It seems org.apache.zookeeper.server.ServerCnxnFactoryTest.testShedConnections_SmallPercentageRoundsToZero{FactoryType}[2] failed in Jenkins:

org.opentest4j.AssertionFailedError: 1% of 1 connection should round to 0 ==> expected: <0> but was: <1>
	at org.apache.zookeeper.server.ServerCnxnFactoryTest.testShedConnections_SmallPercentageRoundsToZero(ServerCnxnFactoryTest.java:106)

However it is successful for me locally on this branch:
