CustomFieldValuePersister fails with PersistenceFieldType.TYPE_UNLIMITED_TEXT

In my add-on, I use, by injection, the OfBizCustomFieldValuePersister to store my customfield values. This instance crashes when I use the getIssueIdsWithValue method and pass it the type PersistenceFieldType.TYPE_UNLIMITED_TEXT. The exception thrown by "findBy" mentions that "textvalue" is an invalid field for the table CustomFieldValue.
