openstack4j中的RestEasyProviderFactory ClassCastException

Question

我已经将我的openstack4j版本升级到了3.0.3 (从v2)，当我在Tomcat中同时使用OKHTTP Connector和HTTPCLIENT Connector运行它时，我遇到了这个错误。

java.lang.ClassCastException: org.glassfish.jersey.server.internal.RuntimeDelegateImpl cannot be cast to org.jboss.resteasy.spi.ResteasyProviderFactory

openstack4j的v2不会出现此问题。

我在maven项目上使用3.0.4版本时也遇到了同样的问题。将依赖升级到3.1.0就解决了这个问题。以下是包含的工件详细信息：

<dependency>
   <groupId>org.pacesys</groupId>
   <artifactId>openstack4j</artifactId>
   <version>3.1.0</version>
</dependency>
