Hi,
When I re-index jira, I get many error similar to the following (only the usernames are different):
2013-10-10 15:53:27,220 indexerPool-1-thread-10 WARN [issue.customfields.impl.AbstractSingleFieldType] Value stored in database is invalid
com.atlassian.jira.issue.customfields.impl.FieldValidationException: User 'clangmeier' was not found in the system
It seems that it's because of deleted users that are still stored as a customfield value in the database. In Jira interface, the custom fields containing deleted users appear empty.
The database integrity checker doesn't find errors. Is there another way to solve that problem than manually delete the users in the database?
