generated models do not have a hashcode that is consistent with equals

[Krishnan Anantheswaran]

.. which means suffering if someone tried to stick these into sets and map keys.

$ cat x.rdl
type Foo struct {
	String bar;
	String baz;
}
$ rdl -ps generate java-model x.rdl

produces

//
// This file generated by rdl 1.4.13. Do not modify!

import com.yahoo.rdl.*;

//
// Foo -

public class Foo {
    public String bar;
    public String baz;

    public Foo bar(String bar) {
        this.bar = bar;
        return this;
    }
    public Foo baz(String baz) {
        this.baz = baz;
        return this;
    }

    @Override
    public boolean equals(Object another) {
        if (this != another) {
            if (another == null || another.getClass() != Foo.class) {
                return false;
            }
            Foo a = (Foo) another;
            if (bar == null ? a.bar != null : !bar.equals(a.bar)) {
                return false;
            }
            if (baz == null ? a.baz != null : !baz.equals(a.baz)) {
                return false;
            }
        }
        return true;
    }
}
