Symptoms
When trying to add a favourite, an error message appears:
Server error while updating favourite
The following appears in the atlassian-confluence.log:
java.lang.NullPointerException

...
In contrast, a normal startup looks like:
2010-01-22 17:29:20,407 INFO [main] [beans.factory.xml.XmlBeanDefinitionReader] loadBeanDefinitions Loading XML bean definitions from class path resource [services/statusServiceContext.xml]

Notice that the labelServiceContext appears in the second log but not the first, meaning in the first log it has not loaded.
Cause
Previous versions of <CONFLUENCE_INSTALL>/confluence/WEB-INF/web.xml did not contain the proper configuration, and the label is not loading. Most likely, the problem occurs when the web.xml file has been copied from an old instance into a new during an upgrade.
The default 3.1 web.xml contains:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:/databaseSubsystemContext.xml,
classpath:/services/cacheServiceContext.xml,
classpath:/services/bandanaServiceContext.xml,
classpath:/services/eventServiceContext.xml,
classpath:/services/pluginServiceContext.xml,
classpath:/services/taskQueueServiceContext.xml,
classpath:/services/permissionsServiceContext.xml,
classpath:/applicationContext.xml,
classpath:/i18NContext.xml,
classpath:/securityContext.xml,
classpath:/productionDatabaseContext.xml,
classpath:/indexingSubsystemContext.xml,
classpath:/searchSubsystemContext.xml,
classpath:/rpcSubsystemContext.xml,
classpath:/upgradeSubsystemContext.xml,
classpath:/wikiSubsystemContext.xml,
classpath:/wikiFiltersSubsystemContext.xml,
classpath:/velocityContext.xml,
classpath:/importExportSubsystemContext.xml,
classpath:/schedulingSubsystemContext.xml,
classpath:/atlassianUserContext.xml,
classpath:/attachmentSubsystemContext.xml,
classpath:/services/baseServiceContext.xml,
classpath:/services/contentServiceContext.xml,
classpath:/services/userServiceContext.xml,
classpath:/services/statusServiceContext.xml,
classpath:/services/labelServiceContext.xml,
classpath:/com/atlassian/confluence/compatibility/compatibility-context.xml,
classpath:/jmxContext.xml,
classpath:/cacheProviderContext.xml
</param-value>
</context-param>
Notice that the 3.1 web.xml contains the classpath:/services/labelServiceContext.xml line, which previous installs did not include.
