Categorizing and Analyzing the Impact of Bugs in Open Source Software

As open source software is gaining popularity, it becomes necessary to do the modifications in the code.
Modifications could be enhancing the functionalities, or bug fixing. Therefore in this paper, we have used Find
Bugs plugin in the Eclipse environment to categorize the different types of bugs in Open Source Software to
study the bug dynamics. We have used various versions of JFreechart software to track and analyse different
types of bugs. JFreechart is open source software. After this CodePro AnalytiX plugin is used in Eclipse
environment to calculate the complexity metrics. Complexity is calculated on each version of JFreechart to
study the reasons for increase or decrease in the number of bugs in each version. The results have shown that
increase or decrease in number of bugs is closely related to average Cyclomatic complexity.
