Hi, I try to migrate my unmaneged extention from Neo4j 2.3.2 (Comunity Edition) to Neo4J 3.0 (CE) . So I updated the Neo4j version in my pom.xml file and rebuild the plugin. After that I copied it into the plugin directory and edited the neo4j.conf as following:
dbms.unmanaged_extension_classes=package.path.to.my.resource=/graph/ When I try to start neo4j I get the following stacktracke: 2016-04-26 12:52:54.297+0000 INFO Starting... 2016-04-26 12:52:54.784+0000 INFO Bolt enabled on localhost:7687. 2016-04-26 12:52:56.589+0000 ERROR Failed to start Neo4j: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@5384a166' was successfully initialized, but failed to start.
