Я пытаюсь построить и использовать базу данных neo4j. Ниже приведен код, который Im использует для создания БД.Ошибка Neo4j: Ошибка при запуске org.neo4j.kernel.impl.factory.CommunityFacadeFactory
String graphDbPath = "C:/Users/abcd/parseJSON2GraphDB";
GraphDatabaseFactory dbFactory = new GraphDatabaseFactory();
GraphDatabaseService graphDb = dbFactory.newEmbeddedDatabase(graphDbPath);
try (Transaction tx = graphDb.beginTx()) {
// Perform DB operations
Node javaNode = graphDb.createNode();
javaNode.setProperty("name", "Duane");
Node scalaNode = graphDb.createNode();
scalaNode.setProperty("name", "Nickull");
tx.success();
}
graphDb.shutdown();
System.out.println("Created Successfully");
ошибка, при которой я получаю при запуске она:

Есть указатели относительно того, что является причиной его?
От быстрых поисков, я попытался несколько решений: 1) Проверьте, если все экземпляры Neo4j уже запущен. 2) Изменена версия neo4j (через maven)
Ничего не работало до сих пор.
