Summary: Warning related to "org.apache.lucene.store.MMapDirectory.lookupProvider " when starting XWiki on Java 25
Issue Type: cid:jira-generated-image-avatar-bae390e8-b66a-493b-b2aa-8fc4628f734a Bug
Affects Versions: 17.10.3
Assignee: Unassigned
Created: 10/Mar/26 15:10
Environment: Windows 11 Pro, Edge 145, using an instance of XWiki 17.10.4 on PostgreSQL 17, Tomcat 11 and Jetty/HSQLDB, Java 25
Priority: cid:jira-generated-image-static-minor-85872b87-c2ca-4f09-ad36-7832580259b6 Minor
Reporter: Ilie Andriuta
Description:

Steps to reproduce

  1. Start XWiki (e.g. 17.10.3 and 17.10.4) on Java 25 (reproduced on both Tomcat 11 and Jetty)
  2. Observe the logs (XWiki console)

Expected results

No (other) warnings are displayed.

Actual results

The following stacktrace is displayed:

10-Mar-2026 13:41:32.680 WARNING [coreLoadExecutor-11-thread-1] org.apache.lucene.store.MMapDirectory.lookupProvider You are running with Java 22 or later. To make full use of MMapDirectory, please update Apache Lucene.

This stacktrace seems different from the one reported on XWIKI-22012 (on Java 21).
