Example 1 with FirewallingConnectionManager

use of com.hazelcast.nio.tcp.FirewallingConnectionManager in project hazelcast-jet by hazelcast.

the class JetSplitBrainTestSupport method createHazelcastInstanceInBrain.

/**

 *         members and its connection manager blocks connections to other brain's members
