You Can’t Please All The Java People, All The Time

But you can confuse them… I don’t envy Mark Reinhold’s job. As Chief Architect of the Java Platform Group at Oracle, he has literally millions of Java developers to keep happy. That’s no simple task. Just before JavaOne, there were a number of announcements made about the Java platform including a move to a strict

A New Day, A New JDK!

Today is the day! After a [rather long] wait, JDK 9 is finally here! JDK 9 has plenty of new features (you can find more details in my presentation, “55 New Features in JDK 9”) but, from a developers perspective doesn’t quite have the excitement we had with JDK 8 and the introduction of Lambda

JDK 9: XXtra Command Line Options

In my last blog entry on JDK 9 compatibility, I included a list of the command line options that had been removed between JDK 8 and JDK 9. For this blog, I thought I’d do the inverse and look at the new command-line options available in JDK 9. I’m going to limit things to the

Faster Java: Do We Really Want It?

Last week I was at the Voxxed Days Bristol event, which was as enjoyable as last year. Bristol appears to have a lot of developers, and there is clearly a thriving startup community there. As ever, there is plenty of interest in Java. Originally, I had been scheduled to deliver my talk on “55 new Features in

Standing At the Nexus of Technology

  Last week I was in Atlanta for the Devnexus conference. This is a well-regarded conference that has been running since 2009, but it was the first time I’d had an opportunity to attend. I delivered two presentations, both of which were new material: “It’s Java Jim, But Not As We Know It” and “55 New

Performance Rendered Visual

I’ve written a couple of blogs in the past about jHiccup, which is a really useful tool for looking at the performance of the platform your Java application is running on. jHiccup can show you things like the real impact of garbage collection pauses on your application. Recently, however, I found another use for it,
