I have a spring-hibernate web application featured with hazelcast version:1.9.4.8
I use default hazelcast configuration rather than spring integration. I use JUnit non-transactional tests for unit tests. I use @Before to shutdown all instances of Hazelcast at first place. And similarly @After to cleanup.
Due to my computer is in my company’s network, I was configuring hazelcast tcp-ip enabled with respective IP’s of whom is going to test and use that application on its own local.
However, whenever I changed IP’s from network ip’s to 127.0.0.1, I cannot make it possible to join multiple members. But before, when ip’s of conf. was like:
192.168.24.27
I need to change it from specific ip adresses to standart like 127.0.0.1 in order to enable different developers also to work tests on their own computers…
Here is a part of my sample unit test:
///
LOG.info("test is begining");
Map map;
int memberSize = 0;
Config config = new Config();
// Hazelcast cluster member 1
final HazelcastInstance customInstance1 = Hazelcast.newHazelcastInstance(null);
assertEquals(2, clusterListener.getMemberSize());
getApplicationMap().put("member2", 2);
// shutdown member 1
customInstance1.getLifecycleService().shutdown();
// Hazelcast cluster new member 1
final HazelcastInstance customInstance2 = Hazelcast.newHazelcastInstance(null);
assertEquals(2, clusterListener.getMemberSize());
getApplicationMap().put("member2_new", 2);
assertEquals(3, getApplicationMap().size());
LOG.info("\n\n *** Hazelcast test is OK. *** \n");
///
Here is the short but related part of my hazelcast configuration for my problem:
…
<port auto-increment="true">5701</port>
<join>
<multicast enabled="false">
<multicast-group>224.2.2.3</multicast-group>
<multicast-port>54327</multicast-port>
</multicast>
<tcp-ip enabled="true">
<interface>127.0.0.1</interface> // it was 192.168.24.27 before and was working
</tcp-ip>
</join>
<interfaces enabled="true">
<interface>127.0.0.*</interface>
</interfaces>

Here the related log:

I would appreciate any help, thanks in advance..
When I upgraded the version of hazelcast from 1.9.4.8 to 2.3.1 the problem is gone.
