java.util.concurrent.locks.Condition.await()
not being called inside a loop.
await()
and related methods are normally used to suspend a thread until some condition becomes true.
As the thread could have been woken up for a different reason,
the condition should be checked after the await()
call returns.
A loop is a simple way to achieve this.
Example:
void acquire(Condition released) throws InterruptedException {
released.await();
}
Good code should look like this:
void acquire(Condition released) throws InterruptedException {
while (acquired) {
released.await();
}
}
