使用FutureTask

Question

尝试使用某些并行计算时遇到以下错误：

SIGSEGV (signal SIGSEGV: invalid address (fault address: 0x430000))

我的方法的一部分＆＃34;产生＆＃34;这个错误看起来如下：

            ...
            ...
            task1 = new FutureTask<>(() -> {
                Core.inRange(hsvMat, new Scalar(0, 120, 120), new Scalar(11, 255, 255), lowerColor);
                return true;
            });

            task2 = new FutureTask<>(() -> {
                Core.inRange(hsvMat, new Scalar(171, 120, 120), new Scalar(184, 255, 255), upperColor);
                return true;
            });
            executor.execute(task1);
            executor.execute(task2);

            try {
                if (task1.get() && task2.get()) {
                    executor.shutdown();
                    Core.add(lowerColor, upperColor, mixedColors);
                }
           return mixedColors;

返回mixedColors时会发生此错误，但仅在调试模式下发生。在没有调试的情况下启动应用程序时，它会通过但没有任何结果，就像这个功能没有发生一样。 没有FutureTask<>的代码工作正常，因此必须存在一些问题，但我不知道是什么。我将不胜感激任何建议。

编辑：

我设法检索了这个堆栈跟踪，但仍未找到解决方案。
