Description
Many content types created by LDAP users are not being indexed properly by confluence. During a full index rebuild, there are several of the following errors in the logs:

This is happening for Attachments and UserStatus, and may happen for several other datatypes as well. It only happens where the LDAP user is missing a full name value in confluence (i.e. the PersonalInformation object referenced by the Attachment has a null fullName value, or the UserStatus has a null fullName value, etc).
This exception should never be thrown, as null values need to be handled in each of the extractors.
Workaround
1) Disable the UserStatusExtractor in the User Status Plugin in Confluence Admin > Plugins.
2) Disable the EmbeddedSubCalendarsExtractor in Team Calendars (if installed)
3) Reindex.
4) Watch for any other stack traces. If there are any, contact support.
Note: make a note of which Extractors you will have to disable in case you need to enable them again.
The above changes should result in:
- The object that any disabled Extractor pertains to will not be searchable
- The rest of the content will be indexed correctly and will be searchable
