我正在尝试在使用Quarkus作为其应用程序框架的Java Web应用程序中实例化一个org.keycloak.admin.client.Keycloak对象。过去，我已经在已部署到Wildfly的应用程序上成功完成了此操作，但是并没有按预期将其转换为Quarkus。我的工厂类实例化Keycloak对象，如下所示：
Keycloak kc = KeycloakBuilder.builder().serverUrl(authServerURL).realm(realmName).clientId(clientID)
.clientSecret(clientSecret).username(adminUsername).password(adminPassword).build();
但是，当我尝试调用工厂方法时，我遇到了以下异常：

我的假设是，这与Resteasy版本不匹配或某些其他依赖项问题有关。但是，我不知道如何解决此问题。有什么建议吗？
更新1：现在已包含完整的堆栈跟踪
答案 0 :(得分：1)
似乎已在Quarkus 1.4（release notes）中修复。
该版本添加了新的扩展名quarkus-keycloak-admin-client（source code）。
