升级到最新的JDK后,我们(在某些机器上)有一个奇怪的OutOfMemoryException.

考虑这个简单的应用:

public class Test
{
    public static void main (String[] args) {
        try {
            java.text.SimpleDateFormat dateFormatter = new java.text.SimpleDateFormat("E dd/MM/yyyy HH:mm");
            System.out.println("formatted date: " + dateFormatter.format(new java.util.Date()));
        } catch (Exception x) {
            System.err.println(x);
            System.exit(1);
        }
    }
}

运行这个小程序将导致此异常(即使在运行时-Xmx2048M -Xms2048):
