  Due to increasingly complex software design and rapid iterative development,
code defects and security vulnerabilities are prevalent in modern software. In
response, programmers rely on static analysis tools to regularly scan their
codebases and find potential bugs. In order to maximize coverage, however,
these tools generally tend to report a significant number of false positives,
requiring developers to manually verify each warning. To address this problem,
we propose a Transformer-based learning approach to identify false positive bug
warnings. We demonstrate that our models can improve the precision of static
analysis by 17.5%. In addition, we validated the generalizability of this
approach across two major bug types: null dereference and resource leak.
