def writeListVector(writer: UnionListWriter, arr: Array[_], pose: Int):

writer.startList()
writer.setPosition(pose)
arr.foreach {
case e: Short => writer.smallInt().writeSmallInt(e)
case e: Int => writer.integer().writeInt(e)
case e: Byte => writer.writeTinyInt(e)
case e: String =>
val rootAllocator = new RootAllocator()
val tempBuf = rootAllocator.buffer(2048)
val bytes = e.getBytes(StandardCharsets.UTF_8)
tempBuf.setBytes(0, bytes, 0, bytes.length)
writer.varChar().writeVarChar(0, bytes.length, tempBuf)

writer.setValueCount(arr.length)
writer.endList()

I use a function like above to write an array to a list vector, everything
is normal except case String. It just returns a empty string list,which every
elements' length is correct, like:
`[["", ""], [""], ["", "", ""]]`
can somebody help me?
