Running JRE 1.6.0 update 5 on a client computer with xMII 12.0

Upgrades to Java-based applications elsewhere in my company are forcing us to consider running xMII 12 (which we're in the process of upgrading to) with Java 1.6.0 update 5 on the client computers. Are you aware of any technical or support issues running v12.0 on this Java version?
