在我们公司，我们做一个项目，使用apache，cassandra。直到最近，我们还用了一个老司机。昨天，我们尝试用最新的4.3.0替换它。我们连接到数据库，一切正常。问题是当我尝试替换ear文件或添加另一个使用相同代码的子项目时。
在这一点上，我得到了这个错误。

我试着在网上寻找这个问题，研究他们的文档。我没有找到解决办法。
我连接到数据库的基本代码。

@PostConstruct
public void start() {
    log.info("start");
    CqlSessionBuilder builder = CqlSession.builder();
    builder.addContactEndPoint(new DefaultEndPoint(new InetSocketAddress("127.0.0.1", 9042)));
    builder.withLocalDatacenter("datacenter1");
    session = builder.build();
}

@PreDestroy
public void stop() {
    log.log(Level.INFO, "stop");
    session.close();
}

我使用wildfly作为服务器。当我替换ear文件或添加另一个具有相同代码的文件时，会出现错误。
有什么办法解决吗？
