执行程序服务和可调用java.lang.IllegalStateException：java.util.concurrent.ExecutionException

Question

我有一个代码，可从其他计算机远程获取JMX指标并将其插入数据库。该代码由Executor Services和Callables实现：

ExecutorService executor = Executors.newWorkStealingPool();
ArrayList<Callable<String>> callables = new ArrayList<>();
for (String i : nhost.getHosts()) {
           callables.add(
                   () -> { sth ; }
}

while (true) {

        executor.invokeAll(callables).stream()
                .map(future -> {
                    try {
                        return future.get();
                    } catch (Exception e) {
                        throw new IllegalStateException(e);
                    }
                })
                .forEach(
                        entry -> ESBRun.display(entry)
                );
        TimeUnit.SECONDS.sleep(sleep);
    }
}

运行一段时间（大约5000次循环）后，它会出错：

该错误包含几种类型的错误，但我不知道是什么原因引起的。我想这是因为获取节点JMX指标时发生错误，但我不知道该如何处理？
