[jira] [Commented] (SLING-13248) Exception while initializing Vanity paths

["Julian Sedding (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-13248?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18098429#comment-18098429 ] 

Julian Sedding commented on SLING-13248:
----------------------------------------

[~joerghoh] and I analysed this issue. It turns out that a "sling:vanityPath" property of type "Date" exists. This is always sorted before any propert of type "String" in the query result. However, the {{PagedQueryIterator}} coerces the value of the "Date" property to a "String", before comparing it using {{Comparable#compareTo()}}.

I.e. the query sorts "(Date)2025-10-14T20:32:01.481Z" before "(String)/acs-commons", but the lexicographic order is "(String)/acs-commons" before "(String)2025-10-14T20:32:01.481Z".

> Came across the case, that the Sling vanity path resolution was not using the cache, but it was resolving the vanity paths always within the {{ResourceResolver.resolve(path)}} codepath.
> It seems to be caused by this exception:
