interrupted-exception

问题 I have seen many times in my code that I get an Interrupted Exception. What is that, and how do I fix it? 回答1: Since I don't know how much you know about Java, how java works exactly and what's concurrency, I'll try to explain as much as possible with nearly no background information needed. At first we're going to take a look at Oracle's documentation of the InterruptedException. Thrown when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or

问题 I have a WEIRD problem with Future.get() in Java. It returns always with an InterruptedException, however the weird thing is that the cause of the Exception is null, so I cant tell who interrupted me.. It gets even worse because I check before calling get(), and the job Future has to do is already done. Here is the code responsible for the output below. f is the Future , and the callable returns a HashMap where Agent is not really relevant. Sorry if there are too many printlines, I'm just

问题 I'm getting frustrated trying to get rid of this pesky exception that displays when my Java program completes: Exception while removing reference: java.lang.InterruptedException java.lang.InterruptedException at java.lang.Object.wait(Native Method) at java.lang.ref.ReferenceQueue.remove(Unknown Source) at java.lang.ref.ReferenceQueue.remove(Unknown Source) at sun.java2d.Disposer.run(Unknown Source) at java.lang.Thread.run(Unknown Source) The source of my woes is the use of the FileSystemView

问题 Should we set the interrupted flag when catching an InterruptedException inside a task managed by an ExecutorService ? Or should we just swallow the InterruptedException ? Example: final ExecutorService service = ...; final Object object = ...; service.submit(() -> { try { while (!condition) { object.wait(); } } catch (final InterruptedException exception) { Thread.currentThread().interrupt(); // yes or no? } }); 回答1: In a task submitted to an ExecutorService , receiving an interrupt is a

问题 In kernel 2.6.11.5, divide zero exception handler is set up as: set_trap_gate(0,&divide_error); According to "Understanding The Linux Kernel", Intel trap gate cannot be accessed by a User Mode process. But it's quite possible that a user mode process also generate a divide_error . So why Linux implement it in this way? [Edit] I think that the question is still open, since set_trap_gate() sets DPL value of IDT entry to 0, which means only CPL=0 (read kernel) code can execute it, so it's
