Camel Simple Expression Language does not like a dot '.' in the parameter name

I have following definition in my blueprint route:

       <setProperty propertyName="destinationEndpoint">
		<simple>${bean:myBean?method=getEndpoint('{{fixedConsumerId}}', '${in.header.contextId}')}</simple>	
        </setProperty>

Where 'fixedConsumerId' is a property placeholder:

fixedConsumerId=FUSEv010

It works ok and the 'getEndpoint' method gets called correctly on the bean referred to by 'myBean'. But when the 'fixedConsumerId' property contains a dot ('.') such as follows:

 
fixedConsumerId=FUSEv01.0

I get the following error when the route attempts to invoke on the bean..

org.apache.camel.RuntimeCamelException: org.osgi.service.blueprint.container.NoSuchComponentException: No component with id 'myBean?method=getEndpoint('FUSEv01' could be found

It seems that the 'simple' language notation gets confused when there is a dot '.' in the parameter name.

Can we improve the Simple Expression Language to allow a dot '.' in the parameter name?
