JRuby SwingWorker-未定义的方法“发布”

我试图在基于Java SwingWorker的JRuby中实现我的worker类。我从以下代码开始,这些代码是我从SwingWorker那里借来的 docs :

class Worker < javax.swing.SwingWorker
  def doInBackground
    publish 'a'
    publish 'b'
    publish 'c'
  rescue
    puts "Error: #{$!}"
  end

  def process(chunk)
    p chunk
  end
end

w = Worker.new
w.execute
sleep 1

我希望看到 过程 方法然而,我犯了一个错误:

Error: undefined method `publish' for #<Worker:0x1daa3d0f>
Did you mean?  public_send

在macOS上的JRuby 9.3.3.0和9.2.9.0中观察到了这种行为。

jruby 9.2.9.0 (2.5.7) 2019-10-30 458ad3e OpenJDK 64-Bit Server VM 17.0.2+0 on 17.0.2+0 +jit [darwin-aarch64]

我错过什么了吗?
