Subject [jira] Created: (BEANUTILS-390) BeanComparator throws exception for null property values

BeanComparator throws exception for null property values
--------------------------------------------------------

                 Key: BEANUTILS-390
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-390
             Project: Commons BeanUtils
          Issue Type: Improvement
          Components: Bean-Collections
    Affects Versions: 1.8.3
            Reporter: Matthew Toso
            Priority: Minor


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.
