Inspectopedia 2025.2 Help

Static member guarded by instance field or this

Reports @GuardedBy annotations on static fields or methods in which the guard is either a non-static field or this.

Guarding a static element with a non-static element may result in excessive concurrency, multiple threads may be able to access the guarded field simultaneously by locking in different object contexts.

Example:

private ReadWriteLock lock = new ReentrantReadWriteLock(); @GuardedBy("lock") public static void bar() { // ... }
