有一个Wildfly Docker 容器实例，从Docker Hub下载，配置了 jms 队列和test用户test密码。Docker 实例使用Dockerfile中的以下代码启动：
FROM jboss/wildfly
COPY target/analysis-engine-1.0-SNAPSHOT.jar /opt/jboss/wildfly/standalone/deployments/
COPY docker-config/standalone-full.xml /opt/jboss/wildfly/standalone/configuration/
RUN /opt/jboss/wildfly/bin/add-user.sh -a -u test -p test --silent
ENTRYPOINT ["/opt/jboss/wildfly/bin/standalone.sh", "-c", "standalone-full.xml", "-Djboss.http.port=8081", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]
standalone-full.xml与原始副本的唯一区别是添加了用于远程通信的JMS 队列，即<jms-queue name="MyQueue" entries="java:jboss/exported/jms/MyQueue"/>
另一方面，在同一台机器上，我使用以下代码创建了一个 Java SE jms 客户端：
public static void main(String[] args) throws JMSException {
try {
String principal = "test";
String password = "test";
Properties p = new Properties();
p.setProperty(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8081");
p.setProperty(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName());
p.setProperty(Context.SECURITY_PRINCIPAL, principal);
p.setProperty(Context.SECURITY_CREDENTIALS, password);
InitialContext context = new InitialContext(p);
ConnectionFactory queueConnFactory = (ConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
Queue jmsQueue = (Queue) context.lookup("jms/MyQueue");
try(JMSContext jmsContext = queueConnFactory.createContext(principal, password)) {
Message message = jmsContext.createTextMessage("This is the message sent to the jms queue");
jmsContext.createProducer().send(jmsQueue, message);
}
} catch (NamingException e) {
e.printStackTrace();
}
}
运行这个JMS客户端，也就是main上面的方法，会导致如下错误：

创建JMSContext. _ _ 这意味着初始化ConnectionFactory并Queue通过JNDI正常工作成功，服务器端日志也可以证明这一点。
问题：如何使JMSContxt的创建成功？
