Low Priority Thread的意思|示意

In this case, the low-priority thread and that other thread are boosted.

在这种情况下，低优先级线程和另一个线程都会被提高优先级。

GC is a thread of very low priority, so a weak reference object may not be collected immediately.

因为垃圾回收器是一个优先级很低的线程，所以弱引用对象也不一定会马上就会被回收。

It's possible that, at the point the high-priority thread tries to acquire the low-priority thread's lock, the low-priority thread itself is blocked on a different lock held by a another thread.

可能存在下面一种情况：高优先级线程试图获取低优先级线程持有的锁，而低优先级线程自身又被另一个线程持有的另一个锁阻塞。

Default JIT compilation, whereby the JIT compiler thread runs at low priority.

默认JIT编译，JIT编译器线程在较低优先级上运行。

An application that must respond to events in a well-defined time has no way to ensure that another low-priority thread won't get scheduled in front of a high-priority thread.

一个必须在精确时间内响应事件的应用程序无法确保不会在一个高优先级线程之前调度另一个低优先级线程。

In the scenario just described, the low-priority thread runs at high priority when lock contention occurs until the point in time that it releases the lock.

在刚刚描述的场景中，发生锁争用时低优先级的线程以高优先级运行，直至线程释放锁。
