“线程中的异常”；neo4j.FileWatcher-1“；java.lang.NoClassDefFoundError:com/sun/nio/file/SensitivityWatchEventModifier

我尝试在WildFly 10中使用新的neo4j版本3.2.1 当我尝试连接到用创建的嵌入式数据库时

this.gdbs=new GraphDatabaseFactory（）.newEmbeddedDatabase（新文件（DB_路径））

我犯了这个错误

10:28:12,960 ERROR [stderr] (neo4j.FileWatcher-1) Exception in thread "neo4j.FileWatcher-1" java.lang.NoClassDefFoundError: com/sun/nio/file/SensitivityWatchEventModifier

同时，该代码可以创建数据库中的节点

try(Transaction trn = this.gdbs.beginTx()){
                this.gdbs.createNode(Label.label("Test"));
                trn.success();
}

您能帮我解决这个问题吗？

默认情况下，所有JDK类都不会暴露于部署中， 在jboss-deployment-structure.xml文件中添加依赖项，如下所示

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
    <deployment>
        <dependencies>
            <system export="true">
                <paths>
                    <path name="com/sun/nio/file"/>
                </paths>
            </system>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

我已经删除了

标签。这个问题似乎与此无关。

无法从Java 9访问，您使用的Java版本是什么？
