java.lang.LinkageError Error in Class Loading
提问by pedr0
I have some problem with my JSystem/Java/Eclipse enviromment.
我的 JSystem/Java/Eclipse 环境有问题。
I get this error and i don't understand what is wrong:
我收到此错误，我不明白出了什么问题：
java.lang.LinkageError: loader constraint violation: loader (instance of jsystem/runner/loader/ExtendsTestCaseClassLoader) previously initiated loading for a different type with name "org/w3c/dom/Document"
I would like know if someone have had a similar issues, I don't think my enviromment is very important for solve it, if I will understand what's happened "undergound" I hope to solve problem myself.
我想知道是否有人遇到过类似的问题，我不认为我的环境对解决它很重要，如果我能理解“地下”发生了什么，我希望自己解决问题。
Thanks a lot in advance.
非常感谢。

I think this happened for me when I included a library twice.
我认为当我两次包含一个库时，这对我来说发生了。
