  == Mixed Version Support ==
  
- Two applications should be able to use one version of the Derby network client driver and
a different version of the Derby embedded driver within the same Java VM without having to
resort to creating specialized classloaders.  This is enabled by supporting forward compatibility

+ Two applications should be able to use one version of the Derby network client driver and
a different version of the Derby embedded driver within the same Java VM without having to
resort to creating specialized classloaders.  Older versions of Derby jars will get their
expected behavior in a mixed version environment regardless of jar ordering.  Newer versions
+ of Derby jars will get new behavior if the newer jar files are loaded first, and older behavior
if the older jar files are loaded first.  This is enabled by supporting forward compatibility
as described below.
