Squeryl fails to reflect in debug mode only

Question

I can't debug (simple run works fine) my unit tests. Squeryl fails with the following exception:

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

java.lang.RuntimeException: 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

I debug using IntelliJ IDEA latest version (13.1.4). Running both in IDEA & in console (sbt clean compile test) works fine.

Switching from jdk 1.8 to jdk 1.7 solved the issue.
