Error in logs when running a workflow from the vSphere web client WARN {} [TypeQualifierToDecoratorConverter] Can't find mapping for:class ch.dunes.model.type.qualifier.TQCallerParameter,[kind:null,name:contextualParameter,value:__NULL__]

I am seeing this error:

WARN  {} [TypeQualifierToDecoratorConverter] Can't find mapping for:class ch.dunes.model.type.qualifier.TQCallerParameter,[kind:null,name:contextualParameter,value:__NULL__]

pop up in the vCO logs a couple of times on a workflow when I attempt to run it from the vSphere web client.  I am wondering if this is somehow contributing to the extended time it takes to render the page.  Has anyone ever seen this or does anyone have a hint on what might be causing this.  The logs are clean when I run the workflow from the vCO client.
