> Using Object.equals to test for equality of a {{CharSequence}} is wrong:
> {code:java}
> CharSequence cs1, cs2;
> cs1.equals(cs2);
> {code}
> The Unit test passes because the test uses the same String on both sides. When I changed
the unit test to wrap the string with a {{CharSequence}} interface it fails.
> It should be replaced with:
> {code:java}
> CharSequence cs1, cs2;
> StringUtils.equals(cs1, cs2);
> {code}
