Handle "undefined" port value in channel details about hop HOT 5 CLOSED

@mheidt can you provide a way to reproduce? It would help testing the workaround.

Not really. I didn't setup the rabbit and its shovel. I am just the developer who is using it.
But I have a fix for the issue, although I think, that the server should return JSON standard compliant responses.
Your suggestion of a custom deserializer is a little bit too much, imho.
Especially because you have to take care of all fields. And if you change ChannelDetails later, you have to take care of the changes in the deserializer as well.
I fixed it like follows:

@JsonProperty("peer_port")
 private String peerPortOrUndefined;

 private Integer peerPort;

...
public String getPeerPortOrUndefined() { return peerPortOrUndefined; }

 public void setPeerPortOrUndefined(String peerPortOrUndefined) { this.peerPortOrUndefined = peerPortOrUndefined; }

 public Integer getPeerPort() {
   if (this.peerPort == null && peerPortOrUndefined != null){
     try {
       this.peerPort = Integer.valueOf(peerPortOrUndefined);
     } catch (Exception e){
       //Ignore
     }
   }
   return this.peerPort;
 }

 public void setPeerPort(Integer peerPort) {
   this.peerPort = peerPort;
 }

and calling getPeerPort() in toString....

@mheidt I pushed a fix, can you try the 3.12.0 snapshot? https://oss.sonatype.org/content/repositories/snapshots/com/rabbitmq/http-client/3.12.0-SNAPSHOT/

from hop.

Yes, I can confirm that it works.
Thanks a lot.
When are you planning to release 3.12.0?

@mheidt Thanks for testing. I released 3.12.0.RC1, the instructions are up-to-date. GA should follow in the next few days if no problem is found.
