On 4 separate conversions to 1.12 the client had issues with some of their Java applications that ran "fine" under 1.4 at the old release of z/OS. We reran with Java 1.6 and the problems no longer existed. The problems had something to do with the way classes are obtained or maintained when a lot of passing object back and forth went on, but I can't remember exactly. I do remember that it didn't appear to matter whether they used the 64bit version of 1.6 or not, both of them executed the code fine.
Most of their Java code ran fine, but there was no reason, once we found some that didn't work, to put any effort into not changing to 1.6. I'm not that good of a Java programmer, but I "think" that there was no functionality lost in 1.6 which was there in 1.4, and I don't think they had to alter their code at all. The stuff I write doesn't really seem to mind what version it runs on, but it's admittedly not that complex.
