Problem for Saga Load Balance Strategy about servicecomb-pack

[WillemJiang]

We should support to apply different strategy on the LoadBalancer. Please feel free to create a JIRA for it. It could be great if you can submit a PR for it.

How to apply different strategies on the Load Balancer? Probably, I have not an in-depth study on it. Please give me some hints. Thank you!
BTW, follow your advice, I created a JIRA for it.

Please point them out when I make some mistakes. Thank you!

Hi Jiang!

I upgraded the Saga program(even though an informality version) and I read the source of 'LoadBalancedClusterMessageSender.java'.
And I thought it was almost same between the last source and the former in terms of function.
How do you think? Or I probably located a wrong position?

By the way, why did you downgrade the JDK version for latest Saga?

@Gannalyo , as the user could use JDK7, we change the code of Omega to support JDK7.
