Property with access=noop results in org.hibernate.PropertyNotFoundException

A property with attribute access="noop" results in an exception being thrown: org.hibernate.PropertyNotFoundException

I have the following property declared:
<property name="errorCount" formula="(SELECT COUNT FROM ECLError WHERE AbstractDeliveryIID = abstractDeliveryIID)" access="noop"/>

Even declaring the property with attribute insert="false" & update="false" results in the same exception being thrown:
<property name="errorCount" formula="(SELECT COUNT FROM ECLError WHERE AbstractDeliveryIID = abstractDeliveryIID)" access="noop" insert="false" update="false"/>

Here is the exception stacktrace (I have replaced the actual classname with XXX_CLASSNAME_XXX:
org.hibernate.PropertyNotFoundException: field [errorCount] not found on XXX_CLASSNAME_XXX
