推荐答案

包com.sun.*和sun.*包含内部内容，一般情况下不应被第三方应用程序使用(可能与您的应用程序一样).

Packages com.sun.* and sun.* hold internal stuff, and should not be used by thirdparty applications (like yours probably) in general case.

自从Java 9中引入了模块系统以来，现在Oracle即使在编译时也保护"了这些软件包.

Since in java 9 the module system has been introduced, now Oracle "protect" these packages even in compile time.

因此，显而易见的方法是摆脱代码中的这种依赖关系. 他们为什么要保护?因为他们保留更改这些东西的权利，所以正如我所说，它被认为是内部的.

So the obvious way is to get rid of this dependency in your code. Why do they protect? Because they leave the right to themselves to change this stuff, its considered internal as I said.

添加:

您可以尝试(不推荐)应用在

You can try (I do not recommend) to apply some "resolution" tools found in this great article (Read "Illegal Access To Internal APIs" chapter), but as the author of this article states, the most straightforward way is to stop using these packages in your code, so consider it as the first bet.
