It is possible to disable plugins that then render jira incapable of restarting

When disabling plugins, it is possible to disable a plugin which then renders jira incapable of restarting.

This can be manifested by disabling the fisheye plugins relating to perforce and leaving the other fisheye plugins enabled and trying to restart jira. It will lead to jira failing due to not being able to find an appropriate constructor to create the plugin Component.

Jira should not allow the disabling of plugins that would render the system incapable of restarting...
