我正在使用旧的Jira版本（6.3.1）。由于硬件限制，在我们能够升级到更新的Jira版本之前，我们必须将其迁移到另一台服务器。新服务器上的设置可以正常工作，也可以毫无问题地导入数据。但成功导入后，登录失败，并出现以下异常：

答案 0 :(得分：0)
好的，我收到了Atlassian支持部门的答复：
根据上面的错误消息，这可能是由于其中一个cwd_group.group_name表中存在空字符串值。 Oracle专门将空字符串视为＆＃39; null＆＃39;导致UserOrGroupCache不断抛出java.lang.NullPointerException的值。这也解释了Postgres数据库中的问题无法重现。
有一个组具有空组名称，重命名它修复了此错误。
