I try to use new neo4j version 3.2.1 with WildFly 10 and when I try to connect to an embedded Database created with

this.gdbs = new GraphDatabaseFactory().newEmbeddedDatabase(new File(DB_PATH))

I have got this error

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

meanwhile node in DB can be created by this code

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

Can you help me to fix this problem?

All JDK classes are not exposed to a deployment by default, add dependencies in jboss-deployment-structure.xml file as below 

<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>
