If you've created a Joomla menu link to Plugin A and you call pluginClassUrl in Plugin B, which has no menu item, you end up with the Itemid from Plugin A. This is more certainly due to the fallback. This behavior should be adjusted for pluginclass so it doesn't fallback to the wrong plugin and give odd URL results. Issue is quickly fixed by generating a menu item to Plugin B so it's not critical or urgent, but isn't as user friendly as it should be.
