Hi!
I am working on a project where some RDF and spatial things are involved. When I tried to take the advantage of your plugin and the semantic plugin neosemantics, some crash happened.

The crash log:

My environment:

• neo4j community edition 3.5.12
• neo4j-spatial-0.26.2-neo4j-3.5.2-server-plugin.jar
• neosemantics-3.5.0.3.jar
• apoc-3.5.0.6-all.jar

When I tried to remove either the semantic or spatial plugin, it works. So I think maybe there is a plugin incompatibility. Do you have any solution? Thanks.
