Unable to Add Comment to Confluence Page Due to NoClassDefFoundError
Symptoms
When attempting to add a comment to Confluence, the comment does not get posted but instead we see a long stack trace, which is not fully displayed - see the screenshot below:
[org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)\n\tat org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235)\n\tat org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)\n\tat com.atlassian.util.profiling.filters.ProfilingFilter.doFilter(ProfilingFilter.java:99)\n\tat
And the following appears in the atlassian-confluence.log:

.....Cause
There seems to be a missing class of certain libraries or plugins. For this case, it seems to be caused by a corruption in plugin/library cache files or an incomplete plugin/library initialization during startup.
Resolution
To solve this issue, you need to clear the Confluence plugins cache, by following these steps:
- Shutdown Confluence
- Ensure the user running Confluence has full read/write privileges to the confluence-home directory.
- Remove the following directories
This will remove the plugin cache files only and will not permanently remove any plugins. These directories will be recreated during the next Confluence startup. However, some third-party plugins may store metadata in these directories, so we recommend creating a temporary backup of the directories.<confluence-home>/bundled-plugins<confluence-home>/plugins-cache<confluence-home>/plugins-osgi-cache<confluence-home>/plugins-temp<confluence-home>/bundled-plugins_language
- Start Confluence
