VersionCheck code may have it round the wrong way - minimum version should be checked

 final Set<Plugin> outdatedPlugins = new HashSet<Plugin>();
        for (String pluginKey : pluginsToCheck)
        {
            final Plugin plugin = pluginAccessor.getPlugin(pluginKey);
            //looks like the plugin isn't installed.
            if (plugin == null)
            {
                continue;
            }
            final VersionNumber maxVersion = new VersionNumber(Float.toString(plugin.getPluginInformation().getMaxVersion()));
            final VersionNumber appVersion = new VersionNumber(getVersionStringWithoutSuffix());
            //now if the plugin's maxVersion is less than to the current app version, this plugin needs to be updated. 
            if (maxVersion.isLessThan(appVersion))
            {
                outdatedPlugins.add(plugin);
            }
        }

Checks a certain subset of plugins installed, to ensure that their minVersion is greater or equal to the current
 * application version.
