Spring Roo 抽象子类 --test 自动失败

Question

我正在使用一个非常简单的域模型，像这样创建...

entity --class ~.domain.Contact --abstract --inheritanceType TABLE_PER_CLASS 
entity --class ~.domain.Student --extends ~.domain.Contact --testAutomatically 
entity --class ~.domain.Family --extends ~.domain.Contact --testAutomatically 

然后我向每个类添加一些字段...

field string --fieldName firstName --class ~.domain.Contact
field string --fieldName secondName --class ~.domain.Contact
field string --fieldName firstName2 --class ~.domain.Family
field string --fieldName secondName2 --class ~.domain.Family

然后我自动生成的测试失败。这对我来说看起来像一个错误，有人找到解决这个问题的方法，或者我可以不在子类上使用 --testAutomatically 吗？ （有点垃圾！）

（我在早期阶段对 Roo 失去了信心，grails 正在召唤我回来......）

这是我的堆栈跟踪......
