-----------------------------------

             Summary: org.apache.jena.atlas.iterator.FilterStack#accept returns incorrect value
                 Key: JENA-698
                 URL: https://issues.apache.org/jira/browse/JENA-698
             Project: Apache Jena
          Issue Type: Bug
          Components: Jena
    Affects Versions: Jena 2.11.0
            Reporter: Matthew Jarvis


To reproduce:

private static class AlwaysAcceptFilter implements Filter<Object> {
  public boolean accept(Object o) {
    return true;
  }
}

private static class AlwaysAcceptFilterStack extends FilterStack<Object> {
  public AlwaysAcceptFilterStack(Filter f) {
    super(f);
  }

  public boolean acceptAdditional(Object o) {
    return true;
  }
}

@Test
public void testAccept() {
  Filter<Object> filter = new AlwaysAcceptFilter();
  FilterStack<Object> filterStack = new AlwaysAcceptFilterStack(filter);
  // this assertion fails
  Assert.assertEquals(true, filterStack.accept(new Object()));
}
