okhttp 3.4.1will go endless loop,when there is a IOException("shutdown")

here is how it go endless loop: in file RetryAndFollowUpInterceptor.java

public Response intercept(Chain chain) throws IOException {

Request request = chain.request();
streamAllocation = new StreamAllocation(
    client.connectionPool(), createAddress(request.url()));
int followUpCount = 0;
Response priorResponse = null;
while (true) {
  if (canceled) {
    streamAllocation.release();
    throw new IOException("Canceled");
  }

  Response response = null;
  boolean releaseConnection = true;
  try {
    response = ((RealInterceptorChain) chain).proceed(request, streamAllocation, null, null);
    releaseConnection = false;
  } catch (RouteException e) {
    // The attempt to connect via a route failed. The request will not have been sent.
    if (!recover(e.getLastConnectException(), true, request)) throw e.getLastConnectException();
    releaseConnection = false;
    continue;
  } catch (IOException e) {
    // An attempt to communicate with a server failed. The request may have been sent.
    if (!recover(e, false, request)) throw e;
    releaseConnection = false;
    continue;
  } finally {
    // We're throwing an unchecked exception. Release any resources.
    if (releaseConnection) {
      streamAllocation.streamFailed(null);
      streamAllocation.release();
    }
  }

when there is a IOException(“shutdown”) when execute response = ((RealInterceptorChain) chain).proceed(request, streamAllocation, null, null); it will go into catch block,and judge if can recover,recover(e, false, request) unfortunately recover() return true,so it will continue and go endless loop

@fabioCollini yup, although that snippet is an older version. I’m working on a fix.
