Only calls that target fields of the current class are reported by this inspection.


class Queue { private final Condition isEmpty = ...; void add(Object elem) { // ... isEmpty.signal(); // warning: Call to 'signal()' without corresponding 'await()' // ... } void remove(Object elem) throws InterruptedException { // ... // isEmpty.await(); // ... } }
