> org.springframework.richclient.table.ShuttleSortableTableModel has hardcoded behaviour for comparing null values. This makes it impossible for Comparators to handle them. As the Java API docs only recommend Comparables (and not Comparators) to throw a NullPointerException if compared to nulls, the hardcoded behaviour should only be executed if no Comparators are specified.
> For example, in my application I need Dates to be sorted in a non-default way. A null value should be larger instead of smaller than anything. This can easily implemented with a Comparator, if ShuttleSortableTableModel lets it treat this case.
