Can you post an SSCCE? http://mindprod.com/jgloss/sscce.html

   My guess it it has something to do with the overloading of the equals()
method, but I can't say much more without seeing some code.

   As an ugly workaround, you could try assertTrue(obj1.equals(obj2)), but
you'd probably be masking a bug somewhere (whether that bug lies in your
code, in jUnit, or in the JVM remains to be seen).

   A suspicion: Does your class implement

    public boolean equals(Object obj) { ... }

or does it instead implement

    public boolean equals(YourClass obj) { ... }

?  If it's the latter, note that this is *not* the method
JUnit will use (nor will most of the rest of Java).

have you debugged into it?

no idea, thie follow simple test shows assertEquals works ok .

package com.amd.sandbox;

import junit.framework.TestCase;

public class EqualsTest extends TestCase {

  public void testEqualsWhereHashcodeIsSameAndEqualsReturnsTrue() {
    Foo f1 = new Foo("hello");
    Foo f2 = new Foo("hello");

    assertEquals("failed!", f1, f2);
    assertEquals("Hashcode differs!", f1.hashCode(), f2.hashCode());
  }

  public void testNotEqualWhenMessageDifferent() {
    Foo f1 = new Foo("hello");
    Foo f2 = new Foo("bye");

    assertFalse("failed!", f1.equals(f2));
    assertFalse("Hashcode the same!", f1.hashCode() == f2.hashCode());
  }

  private static class Foo {

    private String message;

    public Foo(String aMessage) {
      message = aMessage;
    }

    public boolean equals(Object obj) {
      Foo other = (Foo) obj;
      if (this.message.equals(other.message))
        return true;

      return false;
    }

    public int hashCode() {
      return message.hashCode();
    }
  }

}
