[appengine-java] Persist/query test.test1.Test and test.test2.Test

[w]

I have two persistable classes: test.test1.Test and test.test2.Test,
but I can't persist/query objects of these classes right. There is a
simple example shows wrong behavior:

test.TestServlet.java:

package test;

import java.io.IOException;

import javax.jdo.JDOHelper;
import javax.jdo.PersistenceManager;
import javax.jdo.PersistenceManagerFactory;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet {

  public void doGet(HttpServletRequest request, HttpServletResponse
response) throws IOException {
    PersistenceManager pm = pmFactory.getPersistenceManager();
    pm.makePersistent(new test.test1.Test("1", "test1"));
    pm.close();

    pm = pmFactory.getPersistenceManager();
    pm.makePersistent(new test.test2.Test("1", "test2"));
    pm.close();

    pm = pmFactory.getPersistenceManager();
    response.getWriter().println("RESULT:  " + pm.getObjectById
(test.test1.Test.class, "1"));
    pm.close();
  }

  public static final PersistenceManagerFactory pmFactory =
JDOHelper.getPersistenceManagerFactory("transactions-optional");

}

test.test1.TestServlet.java and test.test2.TestServlet.java are the
same except package name, so I missed it:

import javax.jdo.annotations.*;

@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Test {

  public Test(String id, String data) {
    this.id = id; this.data = data;
  }

  public String toString() {
    return getClass().getName() + ": id=" + id + " data=" + data;
  }

  @PrimaryKey
  private String id;

  @Persistent
  private String data;

}

Surprising result I got is following:

RESULT:  test.test1.Test: id=1 data=test2

Expected result:

RESULT:  test.test1.Test: id=1 data=test1
