I am trying to dynamically set up value for 
cassandra-journal.contact-points.

If I am using ConfigFactory.parseString(). It works well.
String name = "cassandra-journal.contact-points=";
String contactPoints = name + "[ipaddress, ipaddres]";
Config overrides = ConfigFactory.parseString(contactPoints);
Config actualConfig = overrides.withFallback(ConfigFactory.load());
ActorSystem system = ActorSystem.create("actor-system", actualConfig);

But if I use Map, it complain about 
 Failed to initialize CassandraSession. It will be retried on demand. 
Caused by: hardcoded v
alue: contact-points has type STRING rather than LIST

Map<String, Object> configurations = new HashMap<String, Object>();
String contactPoints = envHelper.getContactPoints();
configurations.put("cassandra-journal.contact-points", "[ipaddress, 
ipaddress]");
Config overrides = ConfigFactory.parseMap(configurations);
Config actualConfig = overrides.withFallback(ConfigFactory.load());
ActorSystem system = ActorSystem.create("actor-system", actualConfig);


I need to use Map since there are more than one thing I need to configure.

How to resolve this issue?

Thanks and Best Regards,
Yan
