    Description: 
{code}
import org.apache.spark.sql.catalyst.util.CaseInsensitiveMap
var m = CaseInsensitiveMap(Map.empty[String, String])
Seq(("paTh", "1"), ("PATH", "2"), ("Path", "3"), ("patH", "4"), ("path", "5")).foreach { kv =>
  m = (m + kv).asInstanceOf[CaseInsensitiveMap[String]]
  println(m.get("path"))
}

// Exiting paste mode, now interpreting.

Some(1)
Some(2)
Some(3)
Some(4)
Some(1)
{code}

  was:
{code}
  test("CaseInsensitiveMap should be deterministic") {
    var m = CaseInsensitiveMap(Map.empty[String, String])
    Seq(("paTh", "1"), ("PATH", "2"), ("Path", "3"), ("patH", "4"), ("path", "5")).foreach { kv =>
      m = (m + kv).asInstanceOf[CaseInsensitiveMap[String]]
      assert(m.get("path") == Some(kv._2))
    }
