wso2esb v2.1 existance callout mediator causing exceptions

[Harm Verhagen-4]

Hi,

I noticed that whenever I put a call-out mediator in my synapse.xml I get exceptions in the logging.
Everything seems to work fine, but still the exception look alarming.

synapse.xml snippet.
If you put the following in in a sequence I get errors when I press update/save.

       <syn:source xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns2="http://org.apache.synapse/xsd" xpath="s11:Body/getFoo"/>
            <syn:target xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns2="http://org.apache.synapse/xsd" xpath="s11:Body/getFooResponse"/>
        </syn:callout>

exceptions:

JMX is enabled by default... so this is because of the fact that Callout
mediator creates and endpoint and calls the send on that, since that
doesn't have a name the name of the endpoint will be anonymous and on
the second message onwards it will through this error since the endpoint
is going to be anonymous in all the cases.

This has no harm for the functionality though; I will get this fixed for
the next version.

Thanks,
Ruwan
