Description

When using a BeanComparator to sort on a bean property that may contain null values, an exception is thrown. By default, the BeanComparator uses a ComparableComparator internally. ComparableComparator in turn throws a NullPointerException when it attempts to compare to a null value. My proposed solution is extending BeanComparator with a new class, NullSafeBeanComparator, that incorporates logic from NullComparator. I have a working example and will attach it.
