the following snippet:
public void handleInput() { Scanner sc = new Scanner(System.in); int x = 3; while (true) { FutureTask<String> readNextLine = new FutureTask<String>(sc::nextLine); ExecutorService executor = Executors.newFixedThreadPool(10); executor.execute(readNextLine); try { String line = readNextLine.get(x * 1000, TimeUnit.MILLISECONDS); } catch (TimeoutException e) { System.out.println("timed out"); } catch (ExecutionException | InterruptedException e) { e.printStackTrace(); } } } will output "timed out" twice which is expected but after that it will loop throwing ExecutionException, stack follows
java.util.concurrent.ExecutionException: java.lang.IndexOutOfBoundsException: end at java.base/java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.base/java.util.concurrent.FutureTask.get(FutureTask.java:205) at traceCalls.Trace.handleInput(Trace.java:32) at main.main(main.java:11) Caused by: java.lang.IndexOutOfBoundsException: end at java.base/java.util.regex.Matcher.region(Matcher.java:1515) at java.base/java.util.Scanner.findPatternInBuffer(Scanner.java:1089) at java.base/java.util.Scanner.findWithinHorizon(Scanner.java:1791) at java.base/java.util.Scanner.nextLine(Scanner.java:1649) at java.base/java.util.concurrent.FutureTask.run$$$capture(FutureTask.java:264) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834) obviously im doing somwthing wrong, but i cant figure out out what.
