Summary: NoSuchMethodError on ComparisonFailure.getExpected()Ljava/la

Initial Comment:
When comparing Strings that are not equal with assertEquals, I get the following exception using JUnit 4.1.0.1 which is distributed with Eclipse 3.2.0.

Environment is Sun JDK 1.5.0-08 on Ubuntu. 



java.lang.NoSuchMethodError: junit.framework.ComparisonFailure.getExpected()Ljava/lang/String;

I'm using the following test class to produce this error:


import junit.framework.Assert;
import org.junit.Test;


public class JUnitBug_Test extends Assert {
  
  @Test
  public void passingTest() throws Exception {
    assertEquals( "expected", "expected" );
  }

  @Test
  public void failingTest() throws Exception {
    assertEquals( "expected", "actual" );
  }
  
}

Version correction: JDT version is  3.2.2.r322_v20070104-R4CR0Znkvtfjv9-

I don't think it's a VM issue: When I look at the code of
junit.framework.ComparisonFailure, the only method I see is "getMessage()".
The inherited methods don't include a getExpected(), either.

JUnit version is 4.1.0.1

Is my installation broken?

That stacktrace cannot be from Eclipse 3.2.0. It's from a
org.eclipse.jdt.junit4.runtime from Eclipse 3.2.1 or 3.2.2.

Since it happens on the last line of this code snippet ...
	if (exception instanceof junit.framework.ComparisonFailure) {
		junit.framework.ComparisonFailure comparisonFailure=
			(junit.framework.ComparisonFailure) exception;
		comparison= new FailedComparison(
			comparisonFailure.getExpected(), comparisonFailure.getActual());

..., I think this is a VM problem.
