NPEDetector
Null dereference verifier for Java Programs
NPEDetector is a tool for statically detecting the dereferences in Java programs that are safe
and those that could potentially result in NullPointerException. Designed to be a sound verifier, NPEDetector guarantees the safety of proven dereferences but could imprecisely flag safe dereferences as faulty. NPEDetector is built using WALA, Watson Libraries For Analysis.
