Answer 1

When creating a HazelcastInstance using Hazelcast::newHazelcastInstance you can give it a Config instance as parameter. If you don't do that the Config instance is created from classpath-available config files. XmlConfigBuilder can create Config from those files, too.

After you got the Config instance you call Config::setConfigClassLoader and set it to your bundle classloader.

Config config = new XmlConfigBuilder().build();
config.setClassLoader(getBundleClassLoader());
HazelcastInstance hz = Hazelcast.newHazelcastInstance(config);
