How Spring Boot 4’s JSpecify Eliminates NullPointerExceptions

Spring Boot 4 adopts JSpecify’s null‑safety annotations, replacing JSR‑305, to make nullability explicit at compile time; using @NullMarked and @Nullable with tools like NullAway, developers can catch potential NPEs early, reduce defensive checks, improve API contracts, and handle collections and parameters more safely.
