It seems you can't trap any connection errors with this component. If the server isn't listening, the POE::Kernel->run() in the client crashes. The code is trying to parse an HTML error message when it's expecting a JSON string.
bash-3.1$ perl ./BayeuxClient.pl
Failed to JSON decode data (error malformed JSON string, neither array, object, number, string or atom, at character offset 0 (before "<html>\n<HEAD><TITLE...") at /arm/tools/perl/perl/5.8.8/common/lib/site_perl/5.8.8/JSON/Any.pm line 481.
). Content:
<html>
<HEAD><TITLE>Error: Internal Server Error</TITLE></HEAD>
<BODY>
<H1>Error: Internal Server Error</H1>
Cannot connect to 127.0.0.1:80 (connect error 111: Connection refused)
<small>This is a client error, not a server error.</small>
</BODY>
</HTML>
This is using your example from the perldoc.
Specifying an 'ErrorCallback' doesn't work. Neither does trying to trap the kernel 'DIE' signal.
Of course, I could have missed something. I'm new to this POE malarky.
