> log4net.Repository.Hierarchy.Logger declares Hierarchy property as virtual, however,
when reading the value it uses the private field m_hierarchy, which is not the correct value
(and probably null) if a derived class has overridden the Hierarchy property.
> This leads to a NullReferenceException when invoking the IsEnabledFor method, which is
used in the Log method.
> Expected: overriding the Hierarchy property works
> Actual: overriding the Hierarchy property leaves the private field m_hierarchy unset,
which causes NullReferenceExceptions to be thrown
> This issue also appears to apply for Level and m_level.  The EffectiveLevel property
accesses the private m_level field instead of the virtual Level property, which may also lead
to NullReferenceException.
