在macosx 10.13.4，neo4j 3.3.5上，我试图在添加neosemantics插件后启动Neo4j。在开始之前，我从https://github.com/jbarrasa/neosemantics/releases下载了jar文件neosemantics-3.3.0.2.jar，并在neo4j.conf的底部添加了两行
dbms.unmanaged_extension_classes=semantics.extension=/rdf
dbms.security.procedures.whitelist=semantics.*
错误消息
屏幕上出现“数据库已终止...”
neo4j.log文件显示：
