Cyrille Artho commented on GEODE-3584:
--------------------------------------

Thanks. In this case, some of the changes I've tried ended up working not so 
well; in particular, I first wanted to avoid having to write wrapper functions 
for the setters in Builder. Because Java's type checker is too dumb, this ended 
up requiring more typecasts then I thought (in the few hundreds), so I gave up 
on this once I realized how many changes this would entail.
Therefore, my local commit history has some changes that are later (partially) 
reverted again.

Two changes that are perhaps debatable are:

# hostname to hostName for consistency (was lowercase in LocatorLauncher)
# serverPort/serverBindAddress to port/bindAddress for consistency (was 
server-X in ServerLauncher).

However, without these changes, there is more code duplication left.

> Refactor ServerLauncher and LocatorLauncher to eliminate code duplication

> There is some duplication of code in the Launcher classes that can be 
> eliminated. Both classes have methods such as getBindAddress (called 
> getServerBindAddress in ServerLauncher) that could be hoisted into  
> AbstractLauncher class that they both extend. The same goes for the inner 
> State classes of the Launchers; they have methods that could be moved to 
> AbstractLauncher.ServiceState.
