HarmonyOS 类成员无法在线程之间共享数据

@Sendable
export class NoSendableClass {
  static testArray: collections.Array<string> = new collections.Array<string>()
}

function strSort(inPut: InterA): string {
  /// 这里NoSendableClass.testArray是空的，是否能够线程之间共性类成员数据
  for (let i = 0; i < NoSendableClass.testArray.length; i++) {
    console.log(NoSendableClass.testArray[i])
  }
  let newArr = inPut.getName();
  return newArr;
}

NoSendableClass.testArray.push("1")
NoSendableClass.testArray.push("2")
NoSendableClass.testArray.push("3")
NoSendableClass.testArray.push("4")
let task = new taskpool.Task(strSort, new ClassB());
this.gStack.push(task);
taskpool.execute(task).then((result) => {
  this.taskPoolOutPutStr += "Task executed change successfully: " + result.toString() + "\n";
}).catch((e: Error) => {
  this.taskPoolOutPutStr += "Task executed failed: " + e.toString() + "\n";
});

是否能够线程之间共性类成员数据？
