使用Kawa 2.1和OrientDB（社区2.1.10）时，我看到一些奇怪的类加载问题。我的CLASSPATH仅包含与kawa和orientdb相关的jar。
以下代码段：
(! 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中实例化该类。知道这里发生了什么吗？非常有义务提供任何帮助/指针！
最佳答案
似乎您要在字段gnu.math.IntNum中插入
OrientDB不支持。您应该将此IntNum转换为Java类型
