# JSR 305 ## Identification JSR 305 is a Java Specification Request concerning annotations for software-defect detection. Its metadata may appear transitively inside Android packages through third-party Java libraries. ## Notebook evidence [[Scanned_20260730-1806#Page 18 — `Scanned_20260730-1806.pdf`, PDF page 18|PDF page 18]] records `Jsr305_annotations.gwt.xml`, an XML module descriptor, and a repository-relative `//third_party/java/...` path found inside an uncertain APK. ## Evidentiary boundary The resource's presence does not establish active GWT behavior, remote communication, or intentional first-party use. Identify the exact APK, hash, dependency version, and whether the resource is reachable at runtime. ## Relationships [[Google Web Toolkit]] · [[Software Composition Analysis]] · [[Android Package]].
