I have got a new version of a Java Swing Application (DMG file) that I want to test, but it keeps opening the Old version of the application, even though I have deleted the old application. 我已经有了要测试的Java Swing应用程序（DMG文件）的新版本，但是即使我删除了旧应用程序，它仍会继续打开该应用程序的旧版本。 It's like it's opening a cached version. 就像打开缓存版本一样。

This is how I install the application: 这是我安装应用程序的方式：

Open DMG file. 打开DMG文件。
Drag file to Application folder. 将文件拖到“应用程序”文件夹中。

I only see this issue on OS X. On Windows it works fine. 我只在OS X上看到此问题。在Windows上，它工作正常。

I even tried running the jar file directly, and I see the same behaviour; 我什至尝试直接运行jar文件，并且看到了相同的行为。 it works on Windows but on Mac it shows the old version. 它可以在Windows上运行，但在Mac上可以显示旧版本。

I tried the following but I saw the same behaviour: 我尝试了以下操作，但是看到了相同的行为：

Restarting the computer 重新启动电脑
Clearing/Deleting the Java cache (from System Preference>Java>General>Temporary Internet Files>Settings>Delete Files... ) 清除/删除Java缓存（从“ System Preference>Java>General>Temporary Internet Files>Settings>Delete Files... ）
Logging as the Guest user on my mac. 在Mac上以Guest用户身份登录。

Lastly, I have tried this on a different Mac and I do NOT see the issue. 最后，我在另一台Mac上尝试过此操作，但没有看到此问题。 It seems like there is something specifically wrong with my OS X. 看来我的OS X特别有问题。
