grails - Grails/Groovy转换异常

Question

当我尝试使用最新的grails快照编译附加的groovy类时，出现以下异常。我今天从构建服务器上下来。异常(exception)中的主要注释是:如果这不是您自己做的，请将此错误报告给转换的编写者。

异常(exception):

/u01/workspace/grails/grails-spring-social-core/grails-app/domain/grails/plugins/springsocial/UserConnection.groovy: -1: A transform used a generics containing ClassNode grails.plugins.springsocial.UserConnection for the method public static grails.plugins.springsocial.UserConnection create() { ... }
directly. You are not suppposed to do this. Please create a new ClassNode refering to the old ClassNode and use the new ClassNode instead of the old one. Otherwise the compiler will create wrong descriptors and a potential NullPointerException in TypeResolver in the OpenJDK. If this is not your own doing, please report this bug to the writer of the transform.

因此，这看起来像是几个已报告的grails错误，但是它们在插件中被当作bug忽略了。这是grails问题还是常规问题？

谈到这可能是一个令人毛骨悚然的错误...但是这让我头疼。

根本原因是什么？同样，这是grails变换的问题还是这是一个令人讨厌的编译器异常？以下类是我要编译的类:

package grails.plugins.springsocial

import groovy.transform.EqualsAndHashCode

@EqualsAndHashCode(includeFields=true)
class UserConnection implements Serializable {

    String userId
    String providerId
    String providerUserId
    String displayName
    String profileUrl
    String imageUrl
    String accessToken
    String secret
    String refreshToken
    Long rank
    Long expireTime

    static constraints = {
        userId nullable: false
        providerId nullable: false
        providerUserId nullable: false
        displayName nullable: true
        profileUrl nullable: true
        imageUrl nullable: true
        accessToken nullable: false
        secret nullable: true
        refreshToken nullable: true
        rank nullable: false
        expireTime nullable: true
    }

    static mapping = {
        table "UserConnection"
        version false

        id composite:['userId', 'providerId', 'providerUserId']

        userId column:'userId',length:64
        providerId column:'providerId',length:128
        providerUserId column:'providerUserId',length:128
        displayName column:'displayName'
        profileUrl column:'profileUrl'
        imageUrl column:'imageUrl'
        accessToken column:'accessToken'
        secret column:'secret'
        refreshToken column:'refreshToken'
        rank column:'rank'
        expireTime column:'expireTime'
    }
}

谢谢您的帮助!

最终成为Groovy 1.8.3问题。我降级为1.8.2，不再遇到此问题。
