Tried to upgrade JIRA recently on our Win Server 2012 VM (db = SQL Server 2008) from v6.4.12 to v7.05, and then after that failed miserably, to v7.09. Attempts to contact Atlassian support since at least last week have also failed miserably. Launching after the upgrade redirects to a long error message like this:
java.lang.RuntimeException: javax.servlet.ServletException: java.lang.NoSuchMethodError: com.atlassian.jira.security.JiraAuthenticationContext.getLoggedInUser()Lcom/atlassian/crowd/embedded/api/User;
...followed by about 200 lines of error details. Can anyone help?
