Hello,

We encountered a NullPointer using the VirtJenaProvider provided with the 
virtuoso-opensource-5.0.11.
This NullPointer is thrown by the Object2Node(Object o) method of the VirtGraph 
class if the o parameter is null.

A patch is provided in RC version of the virtuoso opensource edition and 
returns the java null value if o is null.

            public static Node Object2Node(Object o)
            {
                        if (o == null) {
                                   return null;
                        }
                        ...
            }

I would like to know why the Node.NULL value of the Jean API hasn't been used?

            public static Node Object2Node(Object o)
            {
                        if (o == null) {
                                   return Node.NULL;
                        }
                        ...
            }
