Java
'wait()' or 'notify()' is not in synchronized context
Warning
New
Last modified: 03 December 2024 Reports calls to wait()
, notify()
, and notifyAll()
that are not made inside a corresponding synchronized statement or synchronized method.
Calling these methods on an object without holding a lock on that object causes IllegalMonitorStateException
. Such a construct is not necessarily an error, as the necessary lock may be acquired before the containing method is called, but it's worth looking at.
Example:
class Sync {
private final Object lock = new Object();
void test() throws InterruptedException {
synchronized (this) {
lock.wait(); // 'lock.wait()' is not synchronized on 'lock'
}
}
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
