notify()
or notifyAll()
made on
java.util.concurrent.locks.Condition
object.
This is probably a programming error, and some variant of the signal()
or
signalAll()
method was intended instead, otherwise IllegalMonitorStateException
may occur.
Example:
class C {
final Lock l = new ReentrantLock();
final Condition c = l.newCondition();
void release() {
l.lock();
try {
c.notifyAll(); // probably 'signalAll()' was intended here
} finally {
l.unlock();
}
}
}
