newInstance 接受一个 Object... 参数，所以当你给它一个 String[] 时它会通过它作为 Object[].

newInstance takes an Object... argument so when you give it a String[] it passes it as the Object[].

你想要的是以下内容，它告诉它你只传递一个参数，而不是数组的内容作为参数.

What you want is the following which tells it you are passing just one argument, not the contents of the array as arguments.

.newInstance((Object) job1.arg_arr())
