After updating JIRA 6.4 to JIRA Software 7.0.5 the server starts with an NoSuchMethodError:
java.lang.RuntimeException: javax.servlet.ServletException: java.lang.NoSuchMethodError: com.atlassian.jira.security.JiraAuthenticationContext.getLoggedInUser()Lcom/atlassian/crowd/embedded/api/User;
What is there to do?
