500.jsp requires a database connection, to report errors caused by database connection pool timeout

XMLWordPrintable

      Whenever the 500 error page is triggered, the jsp tries to retrieve a database connection to report some details about the database settings. If the 500 page was triggered by database connection pool exhaustion (which is very common) this will fail.

      As the database details for the ConfluenceDS datasource cannot change while confluence is running this information should be stored on startup rather than being retrieved on ever error
