> after talking with Justin Bertram on stackoverflow, he said to me :
>
> "It looks like XStream is trying to deal with an OpenWire
> {{org.apache.activemq.command.ExceptionResponse}} message which is coming
> from the broker. This message contains a serialized {{java.io.IOException}}
> and XStream fails to convert this as it is expecting an XML payload instead.
> That's why the exception says:
>
> {{}}
> {code:java}
> Caused by: com.thoughtworks.xstream.security.ForbiddenClassException:
> java.io.IOException{code}
> {{}}
>
> The {{ForbiddenClassException}} is the exception which XStream throws in
> response to the {{java.io.IOException}} which it can't convert.
> It's not clear what is triggering the {{java.io.IOException from broker"}}
>
>
> Does it possible to manage this type of exception?
