 Modify the implementation of

     NAMESPACE_OSGEO_COMMON::Exception::Create(System::IntPtr ex)


 - Change the if (IntPtr::Zero == ex) check to: if (IntPtr::Zero != ex)
 - Have a single return point in the function
 - Avoid trying to create a nested NAMESPACE_OSGEO_COMMON::Exception object
 for
 the nested FDO exception if the nested FDO cause exception is NULL
 - Add a try...catch block so that this method does not throw errors.
