SWT 小程序：swt-win32-3650.dll 已加载到另一个类加载器中

Question

我有多个页面，其中包含用 SWT 编写的 java 小程序。问题是，小程序仅在第一页上加载，要将其加载到另一个页面上，我需要重新启动浏览器，否则我会收到以下错误：

Exception in thread "Thread-27" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: 
    no swt-win32-3650 in java.library.path
    no swt-win32 in java.library.path
    Native Library C:\Documents and Settings\xxx\Local Settings\Temp\swtlib-32\swt-win32-3650.dll already loaded in another classloader
    C:\Documents and Settings\xxx\Local Settings\Temp\swtlib-32\swt-win32.dll: %1 is not a valid Win32 application

我想知道，当带有小程序的浏览器页面关闭时，如何卸载 swt dll？

Answer 1

小程序类：

    @Override
    public void stop() {
        // do this to unload swt dlls
        System.exit(0);
    }
