> 4.3.0-incubating

> In class MQClientAPIImpl, the two functions 
> getDefaultTopicRouteInfoFromNameServer and getTopicRouteInfoFromNameServer 
> almost have the same code. The only difference is the way to handle the 
> situation when topic does not exist. Suggestion to fix this issue:
> 1) Add a new function: public TopicRouteData 
> getTopicRouteInfoFromNameServer(final String topic, final long timeoutMillis, 
> boolean allowTopicNotExist).
> 2) Merge the code from getDefaultTopicRouteInfoFromNameServer and 
> getTopicRouteInfoFromNameServer into the new function so that it can handle 
> both case.
> 3) Change getDefaultTopicRouteInfoFromNameServer and 
> getTopicRouteInfoFromNameServer to call the new function with   
> allowTopicNotExist parameter true or false.
