Apparently the word isn’t getting out so, I’m passing this along (after all, my screen name is jrunrandy!)
JRun 4 Updater 7 is now live on Adobe.com and is publicly available to customers. Updater 7 supports a host of new platforms, upgrades to existing software and bug fixes. To get Updater 7, go to http://www.adobe.com/support/jrun/updaters.html.
If you are running multi-server or standalone ColdFusion 8, there is no need to apply this updater. However, you should apply it if you deployed ColdFusion 8 using the EAR/WAR configuration on JRun.
