Instance member guarded by static field

Reports @GuardedBy annotations on instance fields or methods in which the guard is a static field. Guarding a non-static by a static may result in excessive lock contention, as access to each locked field in any object instance will prevent simultaneous access to that field in every object instance.


private static ReadWriteLock lock = new ReentrantReadWriteLock(); //static guarding field private Object state; @GuardedBy("lock") public void bar() { state = new Object(); }

Supported @GuardedBy annotations are:

  • net.jcip.annotations.GuardedBy

  • javax.annotation.concurrent.GuardedBy

  • org.apache.http.annotation.GuardedBy


  • androidx.annotation.GuardedBy
