Description

[ERROR]: [Error] $SPARK_HOME/mlib-local/src/test/scala/org/apache/spark/ml/linalg/MatricesSuite.scala.866:Value size is not a member of Object
[ERROR]: [Error] $SPARK_HOME/mlib-local/src/test/scala/org/apache/spark/ml/linalg/MatricesSuite.scala.869:Value size is not a member of Object

ERROR: two errors found

Below is the related code:

test("toString") {
  val empty = Matrices.ones(0, 0)
  empty.toString(0, 0)
 
  val mat = Matrices.rand(5, 10, new Random())
  mat.toString(-1, -5)
  mat.toString(0, 0)
  mat.toString(Int.MinValue, Int.MinValue)
  mat.toString(Int.MaxValue, Int.MaxValue)
  var lines = mat.toString(6, 50).lines.toArray
  assert(lines.size == 5 && lines.forall(_.size <= 50))
 
  lines = mat.toString(5, 100).lines.toArray
  assert(lines.size == 5 && lines.forall(_.size <= 100))
}

test("numNonzeros and numActives") {
  val dm1 = Matrices.dense(3, 2, Array(0, 0, -1, 1, 0, 1))
  assert(dm1.numNonzeros === 3)
  assert(dm1.numActives === 6)

  val sm1 = Matrices.sparse(3, 2, Array(0, 2, 3), Array(0, 2, 1), Array(0.0, -1.2, 0.0))
  assert(sm1.numNonzeros === 1)
  assert(sm1.numActives === 3)
}

what shall i do to solve this problem, and when will spark support jdk11?
