com.atlassian.confluence.diff.DiffException: Index: 1706, Size: 1706

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • When the DaisyHtmlDiffer fails, it will only fail once for each locale, and be cached. (I'm pretty sure). However it will store and rethrow whatever exception occurred every time the diff is requested, and the AbstractNotificationsListener will log the exception at error level with full stacktrace. The downsides are: * The misleading appearance of many many diffing failures, which one will falsely indicate a probably performance issue and caching failure. (at least I hope it's false) * Way too much logging, resulting in an actual minor performance issue * Possibly unnecessary memory usage resulting in another performance issue. (I don't know how much is stored within the DaisyDiff exception. My guess is it's less than an actual diff). Example stacktrace: {noformat} 2011-09-12 20:43:56,144 ERROR [http-9080-28] [mail.notification.listeners.AbstractNotificationsListener] sendNotification Send Notification: Error deter mining diff for: page: Policy - Computer Standards v.56 (1696826531).
