我一直在使用neo4j版本3.3.3和java嵌入式连接。
我可以使用单个graphservice（单个数据库）而不会出现任何问题。
我想将几个节点从一个graphservice复制到一个新的graphservice（第二个数据库 - testdb2）。
示例代码：
String test="/home/rrodrigues/work/applications/neo4j-community-3.3.3/data/databases/nocompartment.db";
String test2="/home/rrodrigues/work/applications/neo4j-community-3.3.3/data/databases/test2.db";
GraphDatabaseService graphDatabaseService = new GraphDatabaseFactory().newEmbeddedDatabase(new File(test));
GraphDatabaseService graphDatabaseService2 = new GraphDatabaseFactory().newEmbeddedDatabase(new File(test2));
然而，我有下一个例外：
org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.impl.pagecache.PageCacheLifecycle@6e807e2' failed to transition from stopped to shutting_down. Please see the attached cause exception "Cannot close the PageCache while files are still mapped:

这是一个与Lucene PageCache有关的多个数据库索引的问题吗？
