Grails 3.2.11

我试图定义枚举来保存我的自定义角色组＆＃39;和角色＆＃39;我的服务类中的名称和权限：

import grails.transaction.Transactional

@Transactional
class UserService {

    enum RoleEnum{
        ROLE_SUPERADMIN,
        ROLE_ADMIN,
        ROLE_RECEPTION,
        ROLE_HOUSEKEEPING,
        ;
    }
    enum RoleGroupEnum {
        ROLEGROUP_SUPERADMIN([
            UserService.RoleEnum.ROLE_SUPERADMIN,
            UserService.RoleEnum.ROLE_ADMIN,
            UserService.RoleEnum.ROLE_RECEPTION,
            UserService.RoleEnum.ROLE_HOUSEKEEPING
        ]),
        ROLEGROUP_ADMIN([UserService.RoleEnum.ROLE_ADMIN]),
        ROLEGROUP_RECEPTION([UserService.RoleEnum.ROLE_RECEPTION]),
        ROLEGROUP_HOUSEKEEPING([UserService.RoleEnum.ROLE_HOUSEKEEPING]),
        ;

        private List<RoleEnum> roles

        List<RoleEnum> getRoles() {
            return roles
        }

        RoleGroupEnum(List roles) {
            this.roles=roles;
        }
    }


    def serviceMethod() {
        RoleGroupEnum superadmin=RoleGroupEnum.ROLEGROUP_SUPERADMIN;  
       // Throws groovy.lang.GroovyRuntimeException
    }
}

调用serviceMethod（）会引发以下异常：

    at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callStatic(AbstractCallSite.java:222)
    at UserService$RoleGroupEnum.<clinit>(UserService.groovy:18)

我不知道这个签名来自哪里：UserService$RoleGroupEnum(java.lang.String, java.lang.Integer, UserService$RoleEnum)

出于好奇，我添加了以下构造函数：

    RoleGroupEnum(String wtf1, Integer wtf2, RoleEnum wtf3) {
        log.debug("WTF");
    }

我使用相同的签名获得相同的异常。有人可以解释一下发生了什么吗？
