org.hibernate.mapping.PersistentClass#getProperty does not support composite ids

Description

I have the following mapping:

<class name="com.xpn.xwiki.doc.XWikiLink" table="xwikilinks">
        <composite-id unsaved-value="undefined">
            <key-property name="docId" column="XWL_DOC_ID" type="long" />
            <key-property name="link" type="string">
                <column name="XWL_LINK" index="XWLNK_LINK" length="766" />
            </key-property>
        </composite-id>
        <property name="fullName" type="string" column="XWL_FULLNAME" length="768" />
    </class>

and I was expecting the following to work

persistentClass.getProperty("link")

but it tells me my property does not exist.

When looking at getProperty implementation I can see that it does look at the identifier but only if it's a unique identifier and completely miss the Component identifiers which feels like at least an inconsistency.

I had to add the following workaround before my call to getProperty():

KeyValue identifier = persistentClass.getIdentifier();
            if (identifier instanceof org.hibernate.mapping.Component) {
                Iterator<Property> it = ((org.hibernate.mapping.Component) identifier).getPropertyIterator();

                while (it.hasNext()) {
                    Property property = it.next();

                    if (property.getName().equals(propertyName)) {
                        return getConfiguredColumnName(property);
                    }
                }
            }

            return getConfiguredColumnName(persistentClass.getProperty(propertyName));
