Joe Stein commented on KAFKA-1101:
----------------------------------

[~jbrosenberg@gmail.com] What would you like to see it look more like?

//something like
server = new kafka.server.KafkaServer(kafkaConfig);
server.startup();

I have been writing Java/Scala layers with Cassandra lately will be doing that some more with Kafka now too.

I might be wrong but I think we would need a java based jar wrapping the kafka scala jar to un-abstract the byte codes representations?

So we would have a pom (or ant/ivy or gradle or whatever) for building this kafka-java.jar which would wrap the kafka scala jar and provide more Java like code wrapped for java clients?

> We embed the KafkaServer inside a java service container framework, which makes it easy to deploy and monitor within our infrastructure.  When upgrading to kafka 0.8 from 0.7.2, I ran into an issue with not being able to pass the needed constructor arg (SystemTime), since there doesn't appear to be an easy way to instantiate that from java.  So, I ended up with this janky solution using SystemTime$.MODULE$.
> Could a default constructor be added which assumes a default SystemTime, rather than requiring that here?
> Note, I need to construct a KafkaServer directly, since I need to manage the lifecycle more directly than can be done with KafkaServerStartable.
> {code}
>       // Need to do janky scala MODULE$ dereferencing, in order to get a default value in ctor
>       server = new kafka.server.KafkaServer(kafkaConfig, SystemTime$.MODULE$);
>       server.startup();
> {code}
