CodeSig - array methods not expected

[bishabosha]

Mill 0.11.12 (or main branch)

import mill._

def arrayCopyCommand() = T.command {
  val array = Array("a", "b", "c")
  val hash = array.hashCode
  val cloned = array.clone // invokevirtual Method "[Ljava/lang/String;".clone:()Ljava/lang/Object;
  val clonedHash = cloned.hashCode
  println(s"Original hash: $hash, cloned hash: $clonedHash")
}

Analysing this command will crash, because a method is not expected to be invoked on an array class:

Nice find, should be a quick fix
