Description

If a connection has multiple relationships like the following:

<relationship>C</relationship>
<relationship>B</relationship>
<relationship>A</relationship>

The code was getting all children of "connection" with the name "relationship", then passing those to another method which attempted to get another child element named relationship, which resulted in comparing NO_VALUE to NO_VALUE, so every relationship was considered equal and thus not guaranteed to be sorted.
