Modern programming languages, such as Java and C#, typically provide features that handle exceptions. These features separate error-handling code from regular source code and aim to assist in the practice of software comprehension and maintenance. Nevertheless, their misuse can still cause reliability degradation or even catastrophic software failures. Prior studies on exception handling revealed the suboptimal practices of the exception handling flows and the prevalence of their anti-patterns. However, little is known about the relationship between exception handling practices and software quality. In this work, we investigate the relationship between software quality (measured by the chance of having post-release defects) and: (i) exception flow characteristics and (ii) 17 exception handling anti-patterns. We perform a case study on three Java and C# open-source projects. By building statistical models of the chance of post-release defects using traditional software metrics and metrics that are associated with exception handling practice, we study whether exception flow characteristics and exception handling anti-patterns have a statistically significant relationship with post-release defects. We find that exception flow characteristics in Java projects have a significant relationship with post-release defects. In addition, although majority of the exception handing anti-patterns are not significant in the models, there exist anti-patterns that can provide significant explanatory power to the chance of post-release defects. Therefore, development teams should consider allocating more resources to improving their exception handling practices, and avoid the anti-patterns that are found to have a relationship with post-release defects. Our findings also highlight the need for techniques that assist in handling exceptions in the software development practice.
