Squeryl仅在调试模式下无法反映

Question

我无法调试（简单运行正常）我的单元测试。Squeryl 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

我使用最新版本的IntelliJ IDEA（13.1.4）进行调试。在IDEA和控制台（sbt clean compile test）中都可以正常运行。

Squeryl的哪个版本？如果没有更多关于它失败的模型的信息，那么帮助就很困难。顺便说一下，我经常使用Intellij与Squeryl进行调试而没有任何问题。 - Dave Whittaker

从jdk 1.8切换到jdk 1.7解决了这个问题。
