I tried to use ConfigurationBuilder API with addClusterEnabledCacheManager inside MultiHotRodServersTest.addHotRodServer.

Unfortunality it works on with the old Configuration object, with the Builder the test fails. I tried to find any relevant difference inside configuration, but wasn't successful

So I use a LegacyConfigurationAdaptor to create old config.
Attachmed I've traces from the failing tests and from the working one. Maybe it helps.
