As an Admin, I would not like to see warning messages in the logs for DefaultIndexEngine if it should not be a concern to the admins

Problem Definition

Currently we see the following warnings in the logs:

/rest/greenhopper/1.0/xboard/work/allData.json [atlassian.jira.index.DefaultIndexEngine] Tried to reopen the IndexReader, but it threw AlreadyClosedException. Opening a fresh IndexReader.

 /rest/jpo/1.0/issuelinks/commit [atlassian.jira.index.DefaultIndexEngine] Tried to reopen the IndexReader, but it threw AlreadyClosedException. Opening a fresh IndexReader.

This happens because of the way JIRA provides access to its Lucene index to portfolio/agile. This shouldn't have any negative effects whatsoever. However, this is logged as a warning and would cause problems to JIRA admins trying to figure out if they should perform any corrective measure.

Suggested Solution  

• Change the log entry from WARN to INFO or any other appropriate categorization
  or
• remove the entry to the log entirely.

Workaround 

You may filter out these entries from the logs as follows:

1. Shut down JIRA
2. Add the following lines to the log4j.properties file:

   log4j.logger.com.atlassian.jira.index.DefaultIndexEngine = ERROR, console, filelog
   log4j.additivity.com.atlassian.jira.index.DefaultIndexEngine = false
   

3. Start JIRA again

This should help resolve your issue and reduce the amount of warning messages in your logs generated from this particular class.
