我试图让ProgressMonitorDialog起作用，但由于某种原因它在E4（4.7.2）应用程序中不起作用。但它可以独立运行。
我的所作所为：在标准的E3兼容性处理程序中，我执行以下操作：
new ProgressMonitorDialog(HandlerUtil.getActiveShell(event)).run(false, false, monitor -> {
monitor.beginTask("My Task", 20);
for (int i = 0; i < 20; i++) {
Thread.sleep(100);
monitor.worked(1);
}
monitor.done();
});
当我执行处理程序时，我得到以下异常：

如果您尝试上面的代码，您会发现它有效。因为我省略了破坏代码的行：
DPIUtil.setDeviceZoom(100);
无论我把它放在哪里，打开对话框时都会抛出上述异常。但是我需要该行，因为当前的RCP仍然具有与显示器相关联的缩放，因此当主监视器具有缩放活动时我无法打印。 （有关该问题的更多信息，我收集了所有调查结果in this question。）
有没有办法解决这个问题？我认为其他公司在打印和缩放方面存在同样的问题，因此我必须要做的事情。
