JComboBox和IDeref的Clojure代理给出一个java.lang.VerifyError

Somewhere in my code, I do this:

在我的代码中，我这样做:

(proxy [JComboBox IDeref] []
  (deref [] (.getSelectedItem this)))

While on my machine this works fine, some users reported the following problem:

在我的机器上，这个功能很好，一些用户报告了以下问题:

java.lang.VerifyError: class ggo.igs.gui.widgets.proxy$javax.swing.JComboBox$IDeref$db53459f 
  overrides final method 1®­+1ú h.1®ˆû1ú h

    ggo.igs.gui.widgets$combo_box.doInvoke (widgets.clj:124)
    clojure.lang.RestFn.invoke (RestFn.java:440)

I don't see where I might override a final method, especially not with this weird "name". Any ideas what might be wrong?

我不知道在哪里可以覆盖最终方法，特别是用这个奇怪的“名称”。有什么想法吗?

I would start with checking the JDK version on both environments (yours and your users): java.lang.VerifyError can be the result when you have compiled against a different library than you are using at runtime.

我将首先检查JDK版本在两个环境(您和您的用户):java.lang。VerifyError是针对运行时使用的不同库编译的结果。
