Reports calls to <code>wait()</code> methods that may occur while the current thread is holding two locks.
|
|
<p>
|
|
Since calling <code>wait()</code> only releases one lock on its target,
|
|
waiting with two locks held can easily lead to a deadlock.
|
|
</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
synchronized (lockA) {
|
|
synchronized (lockB) {
|
|
lockB.wait(); //warning
|
|
//thread A is stuck here holding lockA
|
|
}
|
|
}
|
|
|
|
synchronized (lockA) { //thread B can't enter the block and release thread A
|
|
lockB.notify();
|
|
}
|
|
</code></pre>
