SpotBugs

SpotBugs is an open-source static analysis tool that analyzes Java bytecode to detect over 400 bug patterns including null pointer dereferences, infinite recursive loops, concurrency issues, resource leaks, and security vulnerabilities using pattern-based detection techniques inherited from its predecessor FindBugs. The tool integrates seamlessly into development workflows through IDE plugins for Eclipse, IntelliJ IDEA, and NetBeans, as well as build tools including Maven, Gradle, Ant, and Jenkins, providing developers with automated bug detection capabilities that help identify potential errors, performance issues, and code quality problems throughout the software development lifecycle.
