... Cause
This issue occurs when the JAVA installation is corrupted and can not load some classes.
Resolution
Download the JAVA installer from Oracle's site (check our supported platforms page to see which versions are supported), install it and update your JAVA_HOME variable to point to this new location. See this doc for more details about JAVA installation.
If starting Confluence via Windows service, check step two of the workaround section of this KB for instructions to how point the Windows service to a different JAVA installation.
