debugging - Squeryl 仅在 Debug模式下无法反射(reflect)

Question

我无法调试(简单运行即可正常)我的单元测试。 Squeryl 失败并出现以下异常:

error while reflecting on metadata for (Some(private scala.Option
com.company.play.model.db.mapping.Position.orgUnit2id),Some(public scala.Option
com.company.play.model.db.mapping.Position.orgUnit2id()),None,Set(@org.squeryl.annotations.ColumnBase(optionType=class java.lang.Object, name=, length=-1, scale=-1, value=ORG_UNIT2ID))) of class com.company.play.model.db.mapping.Position

我使用 IntelliJ IDEA 最新版本(13.1.4)进行调试。在 IDEA 和控制台(sbt clean 编译测试)中运行都可以正常工作。

从 jdk 1.8 切换到 jdk 1.7 解决了该问题。
