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() {
    // ...
}

Supported @GuardedBy annotations are:

net.jcip.annotations.GuardedBy
javax.annotation.concurrent.GuardedBy
org.apache.http.annotation.GuardedBy
com.android.annotations.concurrency.GuardedBy
androidx.annotation.GuardedBy
com.google.errorprone.annotations.concurrent.GuardedBy
