I notice that the new 3.2.4 release now uses a 1.6 JVM in the server startup scripts. I assume that using 1.6 is not a requirement for running the server or building Java adapters. Do you have any comments on performance, resource consumption or reliability of the server with Java 1.6 vs 1.5 - do you recommend an upgrade for those not already on 1.6 (I expect many are not).
