Crash during upgrade from 4.2.4 to 4.4.1

[Stephan Cleaves]

Getting the following stack trace during the import of exported data (last stage of upgrading 4.2.4 to 4.4.1 manually). Looks like it is related to GreenHopper but maybe that is a red herring. Anyone else seen this? Any known solutions?

Exception thrown during upgrade: java.util.concurrent.ExecutionException: com.atlassian.util.concurrent.LazyReference$InitializationException: java.lang.NoSuchMethodError: com.atlassian.jira.issue.customfields.searchers.UserPickerSearcher.(Lcom/atlassian/jira/jql/resolver/UserResolver;Lcom/atlassian/jira/jql/operand/JqlOperandResolver;Lcom/atlassian/jira/security/JiraAuthenticationContext;Lcom/atlassian/jira/issue/customfields/converters/UserConverter;Lcom/atlassian/jira/bc/user/search/UserPickerSearchService;Lcom/atlassian/jira/issue/customfields/searchers/transformer/CustomFieldInputHelper;Lcom/atlassian/jira/user/util/UserManager;Lcom/atlassian/jira/web/FieldVisibilityManager;)V

Caused by: java.lang.NoSuchMethodError: com.atlassian.jira.issue.customfields.searchers.UserPickerSearcher

Maybe caused by non-installed plugin?

BTW, what about upgrade to 4.3 and then to 4.4.1?
