import com.mysql.fabric.FabricConnection; //导入方法依赖的package包/类
/**
* Test Bug#82094 - ConcurrentModificationException on Fabric connections after topology changes.
*
* This test requires a Fabric instance running with a HA group (ha_config1_group) containing three servers, one promoted to master and failure detection
* turned on.
* Note that removing one or the other secondary server is a distinct case and only one of them causes the reported failure. This is so because of the order
* the elements on the slave servers HashSet, from the ReplicationConnectionGroup object, are iterated. So, we remove one at a time in this test to make
* sure we cover both cases.
