Analysis

From the above table it is evident that adopting a Java app for a different underlying MSR setting (combination of VCS, Bug etc.), requires significant number of changes, while Candoia app remains unchanged. This not only decreases the efforts required to build portable MSR app but also increases sharability aspects.
