Dynamic loading of navigation rules not working

I wanted to load navigation rules at run-time rather than load time for my application.. after downloading the latest nightly build (8th Aug) , I found that although runtimeConfig was getting the new navigation rules, somehow they were not getting used. Upon further investigation I found that NavigationHandlerImpl does not reload the rules if they after modified after load time. Thus no matter how many changes I did to runtimeConfig, they were not reflected in the system. I have resolved the issue, and the patch files are attached for RuntimeConfig and NavigationHandlerImpl
