在使用 Kawa 2.1 和 OrientDB（社区 2.1.10）时，我看到了一些奇怪的类加载问题。我的 CLASSPATH 只包含与 kawa 和 orientdb 相关的 jar。

以下片段：

(! g (com.tinkerpop.blueprints.impls.orient.OrientGraph "remote:localhost/GratefulDeadConcerts"))
(g:addVertex "class:Person" "name" "Jill" "age" 33)
(g:commit)

生成此异常：

我相信 gnu.math.IntNum 实际上已经包含在 Kawa 中，我可以在 Kawa repl 中实例化所述类。知道这里发生了什么吗？非常感谢任何帮助/指针！

似乎您正在插入 OrientDB 不支持的字段 gnu.math.IntNum 。您应该将此 IntNum 转换为 Java 类型
