Open source software used for study in this paper is Joda-time (Java date and time API) and find bugs (find bugs in Java program) and both software used for study were developed using java. This paper is to study the relationship between maintainability and metrics of 16 and 12 different versions of java open source software. This paper is to calculate different metrics over different releases. The result illustrate that these metrics strongly related to the quality of open source software.
