-------------------------------------------------------------
https://issues.apache.org/jira/browse/LANG-1249 might be sufficient, but,
technically the request here is to be able to call custom equal methods by
class type so the burden.
In my implementation, I am technically using 2 different EqualsBuilder
instances, so I am not sure if the bug fix would be enough, but, when I walked
through the code, you could see the ignored fields were lost.
If you have an alternative solution without having to use the root
implementation to drive the equals checks, then I am open to it
ps, gave a few more details on my implementation.

> As a tester, there are times I want to exclude certain fields (like ID) for
> my parent object and its children.
> For example:
> {code}
> class Parent {
> public String id;
> public NormalChild child1;
> public SpecialChild child2;
> //uses ReflectionEqualsBuilder for equals();
> //has custom equalsWithoutID() method;
> }
> class NormalChild extend Child {
> public String name;
> //uses ReflectionEqualsBuilder equals() via inheritence;
> //has custom equalsWithoutID() method;
> }
> class SpecialChild extend Child {
> public String id;
> public String name;
> //uses ReflectionEqualsBuilder for equals() via inheritence
> //has custom equalsWithoutID() method;
> }
> abstract class Child{
> //implementes equals();
> public abstract boolean equalsWithoutID();
> }
> {code}
> If I am running a reflectionEquals with excluding field "id" on my parent
> object, the excludedFields won't be used on my children classes (only
> excludes fields of parent with name). I would like to be able to call the
> custom equalsWithoutID() if its an instance of class Child.
> Currently i need to do a workaround where my equals() checks to see which
> method I was using before executing but its not an ideal solution.
