NoSuchMethodError: java.lang.Long.hashCode

Question

I have the following override of method on hashCode in AbstractORM class:

var _id = Random().nextLong()

override fun getId() = _id         


        

Answer 1

I'm not sure about how to solve your problem, but I'll try to explain why are you getting this exception.

In Java 8 a new static method was added to a Long class:

public static int hashCode(long value)

And since then hashCode() method looks like this:

public int hashCode() {
    return hashCode(this.value); // call Long.hashCode() static method
}

So it seems that you have some issues with Java version.
