Clojure proxy problem with protected method which is called from constructor

test.clj

(ns test
  (:import Test1))

(def test3 (proxy [Test1] []
             (generateTest [] "test3")))

(println (.generateTest test3))
;=> test3
(println (.getTest test3))
;=> test1

Test1.java

// given a Java class like this:
public class Test1 {

    private String test;

    public Test1() {
        this.test = generateTest();
    }

    protected String generateTest() {
        return "test1";
    }

    public String getTest() {
        return this.test;
    }

    private static class Test2 extends Test1 {
        @Override
        protected String generateTest() {
            return "test2";
        }
    }

    public static void main(String[] args) {
        Test1 test1 = new Test1();
        System.out.println(test1.getTest());
        Test2 test2 = new Test2();
        System.out.println(test2.getTest());
    }
}

// running this produces output:
test1
test2
