Question

我正在使用Apache CXF实现对OAuth2.0的支持。我还使用OpenJPA来保留客户端和令牌。访问令牌已正确生成并存储。但是，当它们经过验证并且服务器尝试从数据库中检索令牌时，出现以下异常。我已经检查过，并且查询中设置的令牌值正确。令牌记录存在于表中。 JPA代码由CXF随附的JPA数据提供程序JPACodeDataProvider生成

有人知道是什么问题吗？

崩溃在以下代码的setInverseRelation方法中的JDBCStoreManager中发生：

               ClassMapping cm =
                    (ClassMapping) _conf.getMetaDataRepositoryInstance().getCachedMetaData(pc.getClass());
                FieldMapping[] fmd = cm.getFieldMappings();

cm为null，因此cm.getFieldMappings（）崩溃。 ClassMapping不在元数据缓存中。由于某种原因，缓存仅具有原始类，但是pc.getClass返回一个ENHANCED类。看起来非常像Open JPA中的错误。有人可以确认吗？
