Disconnected thoughts on new J2se 1.5 features...

I just sat through several sessions on the new features in J2SE 1.5 as well as 1.4.2. Here are some disconnected thoughts on what I've heard....

Auto-Update for JRE: This seemed to be a big deal. Apparently, it was supposed to be released in 1.4.2, but was delayed to some serious bugs. I have very mixed feelings on this. I think its great that you can update the VM on users machines, don't get me wrong. What Im worried about is how you are going to specify which VM your application is using. Lets say that your application (like most of mine) can only run on a single VM version due to bug fixes or something between versions. Then my client auto-updates the VM and my app breaks. I have heard some hype about this new JRE client management thing. Hopefully that will rock my world!

JSR 166: This is the first I've heard of this-- I must admit I dont read the JSR list before I go to bed each night. Apparently, Doug Lea (esteemed writer of a great Java Threading Book -- http://www.amazon.com/exec/obidos/tg/detail/-/0201310090/qid=1055290829/...), is working with Sun to help them create a built in concurrency API. That rocks!

JSR 163: JVM Profiling. When I was working at JP Morgan, we spent many hours and a lot of headaches trying to get accurate profiling of our deployed clients. Anything in this direction is a huge help. Rock on!

I'm out.
