似乎Thread.State.NEW崩溃了我的Scala REPL。如何正确测试线程是否已启动？
scala> Thread.State.NEW
ReplGlobal.abort: Unknown type: <notype>(NEW), <notype> [class scala.reflect.internal.Types$UniqueConstantType, class scala.reflect.internal.Types$NoType$] TypeRef? false
error: Unknown type: <notype>(NEW), <notype> [class scala.reflect.internal.Types$UniqueConstantType, class scala.reflect.internal.Types$NoType$] TypeRef? false
