Java break / label语句可以在字节码混淆中作为“goto”吗？

我试图在反编译一些 Java .class文件之后对其进行反混淆,我遇到了一些代码,其中使用标签的方式不认为它们可以被使用.我不知道这是否是反编译器误解标签的错误,或者如果代码是以这种方式有意混淆的.换句话说,在Java字节码中可以使用这样的标签？

请注意,标签显示在相关的break语句之后,而不是之前.它几乎似乎被用作一个goto,而不是一个标签被用来走出一个循环.还有没有循环,所以我有点困惑,他们应该如何在这里使用.

这里发生了什么？我在评论中标记了3个标签(###)

      if (i != 99)
