Jason Howk commented on JENKINS-13865:
--------------------------------------
One more update: This appears to be due to the chosen preamble/postamble
chosen.
public static final String PREAMBLE_STR = "\u001B[8mha:";
public static final String POSTAMBLE_STR = "\u001B[0m";
Per RFC, JSON is unicode. (http://www.ietf.org/rfc/rfc4627) and the choice of
the ascii control codes violates the JSON agreement (i.e. use of the brackets
as they are structural characters)

> Looking at the source, the hudson.model.queue.CauseOfBlockage class appears

> public String getShortDescription() {
> return
> Messages.Queue_WaitingForNextAvailableExecutorOn(HyperlinkNote.encodeTo("/computer/"+
> node.getNodeName(), node.getNodeName()));
> }
> The nodename is attempting to be encoded with HyperlinkNote:
> public static String encodeTo(String url, String text) {
> try {
> return new HyperlinkNote(url,text.length()).encode()+text;
> } catch (IOException e) {
> // impossible, but don't make this a fatal problem
> LOGGER.log(Level.WARNING, "Failed to serialize
> "+HyperlinkNote.class,e);
> return text;
> }
> }
> Which calls the supers encode() method:
> public String encode() throws IOException {
> return encodeToBytes().toString();
> }
> And finally encodeToBytes():
> private ByteArrayOutputStream encodeToBytes() throws IOException {
> ByteArrayOutputStream buf = new ByteArrayOutputStream();
> ObjectOutputStream oos = new ObjectOutputStream(new
> GZIPOutputStream(buf));
> oos.writeObject(this);
> oos.close();
> ByteArrayOutputStream buf2 = new ByteArrayOutputStream();
> DataOutputStream dos = new DataOutputStream(new
> Base64OutputStream(buf2,true,-1,null));
> buf2.write(PREAMBLE);
