I have made a simple program that makes kaffe dump core.

sh-2.02$ cat Test.java
import java.util.HashMap;

public class Test {

  private String sss1;
  private String sss2;
  private String sss3;
  private String sss4;
  private String sss5;
  private String sss6;
  private String sss7;

  public static void main(String args[]) throws Exception {
    new Test();
  }

  public Test() throws Exception {
 
    Driver drv = new Driver();

    HashMap hm = new HashMap();
    drv.setHandler(new HashMapMaker(hm));
    drv.handle();

    drv.setHandler(new Test1(hm));
    drv.handle();
  }

private class Test1 extends Handler {

  public Test1(HashMap hm) throws Exception {

    sss1 = (String)(hm.get("sss1"));
    System.err.println(sss1); System.err.flush();
    sss2 = (String)(hm.get("sss2"));
    System.err.println(sss2); System.err.flush();
    sss3 = (String)(hm.get("sss3"));
    System.err.println(sss3); System.err.flush();
    sss4 = (String)(hm.get("sss4"));
    System.err.println(sss4); System.err.flush();
    sss5 = (String)(hm.get("sss5"));
    System.err.println(sss5); System.err.flush();
    sss6 = (String)(hm.get("sss6"));
    System.err.println(sss6); System.err.flush();
    sss7 = (String)(hm.get("sss7"));
    System.err.println(sss7); System.err.flush();
    }

    public void handle() {}

}

private class HashMapMaker extends Handler {

  private HashMap hm;

  public HashMapMaker(HashMap hm) {
    this.hm = hm;
  }
  public void handle() {
    hm.put("sss1","sss1");
    hm.put("sss2","sss2");
    hm.put("sss3","sss3");
    hm.put("sss4","sss4");
    hm.put("sss5","sss5");
    hm.put("sss6","sss6");
    hm.put("sss7","sss7");
  }
