Custom field searcher module: com.atlassian.jira.toolkit:lastcommentersearcher is invalid. Null being returned

[Gianna Migliorisi]

After upgrading to JIRA 6.0 we seem to be receiving a substatianl amount of these errors in the logs:

Custom field searcher module: com.atlassian.jira.toolkit:lastcommentersearcher is invalid. Null being returned

Anyone know what this could be?

• Find the custom field that is causing this, e.g. on mysql:

  select * from customfield where CUSTOMFIELDSEARCHERKEY = "com.atlassian.jira.toolkit:lastcommentersearcher"

  note the value of the field "cfname"

• find the cfname at $BASEURL/secure/admin/ViewCustomFields.jspa, click "Edit" next to it.
• Pick a new search template (or if it says "There are no search templates for this custom field type", just ignore that)
• important: click SAVE

• check the database 

  select * from customfield where CUSTOMFIELDSEARCHERKEY = "com.atlassian.jira.toolkit:lastcommentersearcher"

  -> should be empty

I think you are using jira-toolkit plugin and just check that plugin version is compatible with JIRA 6.0 and also for any deprecated kind of things.
