进入同步块时抛出IllegalStateException表示什么?我有时在线程的运行方法中看到这种情况:
public void run() {
while (true) {
int n = 0;
synchronized (service) { // IllegalStateException
n = processPendingRequests();
}
/*
* If n > 0, we processed at least one element, in which case we
* immediately check the queue again until it was empty.
*/
if (n == 0) {
sleep();
continue;
}
}
}
service
对象可以引起IllegalStateException
吗?怎么样? 最佳答案
根据Java Language Specification,“已同步”语句不会引发“ IllegalStateException”。因此,就我所知,语言规范是错误的,您使用的是不合格的JVM,还是您误解了程序的行为。
关于java - 尝试输入同步块(synchronized block)时发生IllegalStateException,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/2297496/
