> The following line does not work:
>   Restrictions.eq("class", Bike.class)
> because 
>   SingleTableEntityPersister.getDiscriminatorSQLValue()
> returns the discriminator value quoted with single quotes. However JDBC needs the string without quotes.
> Workaround:
>   Restrictions.eq("class", Bike.class.getName())
> This works fine for the default discriminator values
> Patch in CriteriaQueryTranslator.getTypedValue(Criteria subcriteria, String propertyName, Object value):
>   if(stringValue != null && stringValue.length() > 2 && stringValue.startsWith("'") && stringValue.endsWith("'") ) {
>     // remove the single quotes
>     stringValue = stringValue.substring(1, stringValue.length() - 1);
>   }
