FP commented on JSPWIKI-1131:
-----------------------------
I built 43a15c85600d33054eec8fea8c7b622dd582d493 via `mvn clean package` and
updated our installation. The exception when a user saves the page is now gone.
But I noticed the following:
* New pages are indexed immediately: created a new page »TestLucene1« and
provided the following content: »correct horse battery staple«. The search for
each of the words above presented the »TestLucene1« page.
* Edited 3 randomly selected pages and also added the content »correct horse
battery staple« to them. The search for each of the words above found the page
»TestLucene1« as before but none of the randomly edited pages.
One of the 3 edited pages is called »Changelogs«. With debugging enabled, I can
see these lines in the log:
{code:java}

In my opinion, the search results should pop up as soon as indexing is complete
as depicted in the logs. This is not the case.

> Project: JSPWiki
> Issue Type: Bug
> Components: Search
> Affects Versions: 2.11.0-M7
> Environment: * Debian 10
> * Tomcat 9: 9.0.31-1~deb10u2
> * OpenJDK-JRE 11: 11.0.7+10-3~deb10u1
> * JSPWiki 2.11.0-M7
> Reporter: FP
> Priority: Critical
> Attachments: exception.txt
>
>
> It seems that the lucene search index is not updated when a user edits an
> existing page or creates a new page. In both cases, the page is not found
> when someone searches for it.
> Search works as expected when:
> * Tomcat is stopped
> * The files in the {{lucene}} directory are removed
> * Tomcat is started
> * Wait until the Lucene Indexer thread finishes reindexing
> The following exception occurs when a page is edited (full stack trace
> attached):
> {{java.io.NotSerializableException: org.apache.wiki.WikiContext}}
