> Getting "java.lang.ClassNotFoundException" when loading datacache plug-in
> which is a class outside of OpenJPA package.
> This happens when loading the class as DatCache plug-in but it can
> potentially happen to any plug-in classes that reside outside of OpenJPA
> package. In order to load these classes, the fix is to get the class loader
> (by calling findDerivedLoader with no interface loader, loader = null) to
> load it again when the current class loading fails and the target class is
> not part of OpenJPA package. The same exception is still thrown if the
> second attempt fail or the target class is actually part of OpenJPA.
> Please see the patch for detail changes.
