To reproduce run the following code:
{code}
Ignition.start(new IgniteConfiguration().setIgniteInstanceName("server-1"));
Ignition.start(new IgniteConfiguration().setIgniteInstanceName("server-2"));

Ignition.setClientMode(true);

Ignite ignite = Ignition.start();

IgniteSet<String> set = ignite.set("my-set", new CollectionConfiguration().setCacheMode(CacheMode.REPLICATED));

for (String s : set) {
    System.out.println(s);
}
{code}
