Here are two potentially related , posts .这里有两个可能相关的帖子。 Notice you're getting an Error, not an Exception, so that is interesting.
请注意,您收到的是错误,而不是异常,所以这很有趣。 You might try running your JVM with -verbose to see where each class is getting loaded from, to see if maybe you're compiling with one class/jar, but accidentally running with another.
您可以尝试使用 -verbose 运行 JVM 以查看每个 class 是从哪里加载的,以查看您是否正在使用一个类/jar 进行编译,但不小心与另一个类/jar 一起运行。
Also notice from the error that the packages are slightly different "org.mortbay.util" vs. "org.mortbay.jetty", so the UTF8StringBuffer constructor would need to be more visible.另请注意,包与“org.mortbay.util”与“org.mortbay.jetty”略有不同,因此 UTF8StringBuffer 构造函数需要更加可见。 But again, normally a compiler would catch that.
但同样,通常编译器会捕捉到这一点。
I realize this isn't a full answer, to be sure, but at least a couple places to start looking.我意识到这不是一个完整的答案,可以肯定的是,但至少有几个地方可以开始寻找。
