There is one piece of news from IBM‘s i/OS 7.1 roll-out that didn’t generate a lot of attention in the System i community, but is important for programmers who develop in Java as well as their customers. Starting with i/OS 7.1, IBM no longer supports the “Classic” Java Virtual Machine (JVM) that Rochester developed years ago specifically for OS/400. This leaves the platform with two JVMs: one 32-bit and the other 64-bit. IBM says that performance and cross-platform compatibility will improve with the new JVMs, although some developers may need to fiddle with their apps to make them work.
