Ted Yu updated LENS-954:
------------------------
Description:
{code}
private void waitUntilNotEmpty() throws InterruptedException {
conditionalWaitLock.lock();
try {
notEmpty.await();
} finally {
conditionalWaitLock.unlock();
}
{code}
>From
>http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Object.html#wait%28long%29
> :
A thread can wake up without being notified, interrupted, a so-called spurious
wakeup. While this will rarely occur in practice, applications must guard
against it by testing for the condition that should have caused the thread to
be awakened.
