Attachment: commons-lang3-LANG-637.patch
DiffList.java
DiffBuilder.java
Diffable.java
Diff.java
DiffTest.java
DiffListTest.java
DiffBuilderTest.java
I've attached my latest work on this issue (both as individual files and a
patch). I believe the DiffBuilder is now complete for the non-reflection use
case.
I will now work on adding reflection support. I welcome any comments on the
attached.

> The ToStringBuilder and ReflectionToStringBuilder are great tools for
> everyday development.
> We use them to show all the properties in an object, which comes handy
> especially for testing.
> However, JUnit with its assertEquals() just outputs the toString() of the two
> compared objects. For complex objects, this becomes unreadable.
> So, it would be great to have a DifferenceBuilder with a
> ReflectionDifferenceBuilder implementation to be able to get only the
> differing properties of two objects. The question is whether the two objects
> would have to be of the same type or not.
