编译时的Java.lang.ArrayIndexOutOfBoundsError

Question

因此intellij编译器在编译时破坏了。根据我的理解，索引越界是一个运行时错误。怎么能在编译时发生？以下是我正在尝试为ScalaTest编译的内容：

class ConfigurationTest extends FlatSpec{
  behavior of "Configuration"
  it should "have a full configuration" in {
  val dashboard = ConfigurationService.getDashboardConfig("1")
  val dTest = write(dashboard)
  val mockFormat =//Really long Json Object as a string >6000 lines


  val testObj = read[JDashboard](mockFormat)
  assert(dTest.equals(mockFormat))
}
 implicit var formats = org.json4s.native.Serialization.formats(NoTypeHints)
}

由于它是在intellij之外构建的，我假设intellij的内部jvm在某处有限制，但为什么会发生这种情况呢？
