Description

The EqualsBuilder.append(Object[] lhs, Object[] rhs) gives a Nullpointer in
cases of multi dimensional arrays with null fields when reflectEqual an object
containing a 3D Object array.

Fix:
<...>
for (int i = 0; i < lhs.length && isEquals; ++i) {
// Fix when element is null
if ( lhs[i] != null ) {
Class lhsClass = lhs[i].getClass();
if (!lhsClass.isInstance(rhs[i]))

{ isEquals = false; //If the types don't match, not equal break; }

}
append(lhs[i], rhs[i]);
}
