[Java] 为什么不要使用 async void的原因分析

public class testappservice : itestappservice
{
  private readonly ibackgroundjobmanager _backgroundjobmanager;
  public testappservice(ibackgroundjobmanager backgroundjobmanager)
  {
  _backgroundjobmanager = backgroundjobmanager;
  }
  public task getinvalidoperationexception()
  {
  throw new invalidoperationexception("模拟无效操作异常。");
  }
  public async task<string> enqueuejob()
  {
  await _backgroundjobmanager.enqueueasync<bg, string>("测试文本。");
  return "执行完成。";
  }
}
public class bg : backgroundjob<string>, itransientdependency
{
  private readonly testappservice _testappservice;
  public bg(testappservice testappservice)
  {
  _testappservice = testappservice;
  }
  public override async void execute(string args)
  {
  await _testappservice.getinvalidoperationexception();
  }
}

internal static void throwasync(exception exception, synchronizationcontext targetcontext)
{
  var edi = exceptiondispatchinfo.capture(exception);
  // 同步上下文是空的，则不会做处理。
  if (targetcontext != null)
  {
  try
  {
    targetcontext.post(state => ((exceptiondispatchinfo)state).throw(), edi);
    return;
  }
  catch (exception postexception)
  {
    edi = exceptiondispatchinfo.capture(new aggregateexception(exception, postexception));
  }
  }
}

public class bgasync : asyncbackgroundjob<string>,itransientdependency
{
  private readonly testappservice _testappservice;
  public bgasync(testappservice testappservice)
  {
  _testappservice = testappservice;
  }
  protected override async task executeasync(string args)
  {
  await _testappservice.getinvalidoperationexception();
  }
}
