Hi Paul, Comment is not a reserved word, there are no reserved words for what property keys you can use.
Are you also indexing that "Comment" property? It looks like the exception originates from the index component. If so we need to find a work around for that. I can see that you are running this on windows. I'm wondering if this could be the index component trying to create some file (for storing the index) that your file system rejects. Which versions of Neo4j-kernel and Neo4j-index are you using? Have you isolated this so that it is only a "Comment" property being indexed, or are there other indexes to factor in as well?
