【中文标题】scala-native 中的布尔字符串解析行为

【英文标题】：boolean string parsing behaviour in scala-native

【问题描述】：

正常解析代码在缩放原生端（编译后）给出以下异常的原因可能是什么：

 java.lang.IllegalArgumentException: For input string: "false"
at scala.collection.immutable.StringLike$class$.parseBoolean(Unknown Source)
at scala.collection.TraversableLike$$anonfun$map$1.apply(Unknown Source)
at scala.collection.AbstractIterator.foreach(Unknown Source)
at scala.collection.TraversableLike$class$.map(Unknown Source)
at example.Main$.main(Unknown Source)
at <none>.main(Unknown Source)
at <none>.__libc_start_main(Unknown Source)
at <none>._start(Unknown Source)
at <none>.(Unknown Source)
java.lang.RuntimeException: Nonzero exit code: 1

数据：解析以下行

203358,99103,false,3.6,1.0,,0,0.0,0.0,0.0,None,None,None,-1,0

Scala 中的代码：

val objArr=line.split(",")

 objArr(2).toBoolean
