Static analysis tools can be used to help programmers identify problems in their code. However, these tools often assume that developers have some programming background knowledge, so they can be hard to use in an educational context. We investigated the most common FindBugs errors from student code submissions and determined those errors that were related to incorrect solutions to problems and potential struggling for students. FindBugs is a static analysis tool that looks for incorrect patterns in Java bytecode analysis to identify potential coding flaws. For the common errors, we rewrote some of the original FindBugs messages to help students more easily understand the problems with their code. We found that students with at least one FindBugs warning in their final submission to an assignment had more submissions, longer work times, and lower correctness scores than students who did not have a FindBugs warning in their final submission. Adding modified FindBugs feedback to the automated grader resulted in students making fewer submissions and decreasing the length of time required to complete assignments.
