Since the announcement of Java Kernel and improved patching almost two years ago, I was really curious how it will work in real world. I have to say the update works really smoothly, at least at XP and Vista machines. At the XP machine I had Java 6 update 7 installed, which was upgraded to update 10, and few weeks later to 11. The whole update procedure was fast, completed in only few minutes, and painless. The same is true for my Vista machine. I was only asked to shutdown Firefox, Netbeans and Eclipse during the update process - it was the one and only interaction.
Kudos to the engineers - the update procedure is fast and simple (also simple enough for consumers), the incremental patching process seems to work as well; it would be impossible to download the whole JDK / JRE in about two minutes in my case - I had really bad connection.
These are good news - Java6u10/11 is the foundation of javafx. (JavaFX looks interesting as well so far).
