      Description

      Exporting to GraphML throws an error if there are nodes with a List Cardinality and multiple values set for a property. This works fine when exporting to GraphSON.

      The exception thrown is:

      java.lang.IllegalStateException: Multiple properties exist for the provided key, use Vertex.properties(name)at org.apache.tinkerpop.gremlin.structure.Vertex$Exceptions.multiplePropertiesExistForProvidedKey(Vertex.java:179)
      {{ at org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerVertex.property(TinkerVertex.java:75)}}
      {{ at org.apache.tinkerpop.gremlin.structure.io.graphml.GraphMLWriter.writeVertices(GraphMLWriter.java:315)}}
      {{ at org.apache.tinkerpop.gremlin.structure.io.graphml.GraphMLWriter.writeGraph(GraphMLWriter.java:193)}}
