Well, I think it does not.

If there is at least one entry in the database for the current tuple, it
just creates a random UUID but without checking if that UUID already
exists. But in case of a collision, the database insertion may raise an
SQLException.

See functions getStoredId and createPersistentId at
StoredIDDataConnector.java:

http://svn.shibboleth.net/view/java-shib-common/trunk/src/main/java/edu/internet2/middleware/shibboleth/common/attribute/resolver/provider/dataConnector/StoredIDDataConnector.java?view=markup

and function storePersistentIdEntry at StoredIDStore.java:

http://svn.shibboleth.net/view/java-shib-common/trunk/src/main/java/edu/internet2/middleware/shibboleth/common/attribute/resolver/provider/dataConnector/StoredIDStore.java?view=markup
