JIRA unable to start after an upgrade due to java.lang.IncompatibleClassChangeError
The following appears in the
java.lang.RuntimeException: org.apache.jasper.JasperException: javax.servlet.ServletException: java.lang.IncompatibleClassChangeError: Found interface com.atlassian.jira.plugin.navigation.TopNavigationModuleDescriptor, but class was expected
There are incompatible plugins in JIRA which is causing the application failed to start after the upgrade.
- Stop JIRA
- Backup <jira-home-directory>/plugins/installed-plugins/
- Remove <jira-home-directory>/plugins/installed-plugins/
- Start JIRA
This will allow JIRA to successfully startup again. Next, install only the compatible plugin into JIRA. You may check the plugins compatibility matrix and download them from here: https://marketplace.atlassian.com/.
