Unfortunately, the finalizer thread was running at a lower priority than another application thread, so objects weren't getting finalized at the rate they became eligible for finalization.

遗憾的是，终结方法线程的运行优先级要低于另一个应用线程，因此在另一个应用线程中的对象变得可以被终结时，它们不能被终结。

When a finalizer throws an exception that it does not handle, the runtime prints the exception stack trace to the console and then allows the finalizer thread to resume running finalizers.

当终结器引发它无法处理的异常时，运行时将把异常堆栈跟踪打印至控制台，然后允许终结器线程继续运行终结器。
