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
JDK 9 is in the final phases of development, heading towards release on September 21st. The public review consideration ballot for the Java Platform Module System was passed [almost] unanimously, and so everything is now back on track. You can download the Azul Zulu builds of (Early Access) OpenJDK 9 here. Recently I’ve been doing
Recently Gartner released a report advising their clients to look carefully at their use of Java SE to ensure compliance with the Java SE terms of use. We encourage you to do the same, and invite you to explore open source Java alternatives like Zulu and Zulu Enterprise. Azul’s Zulu products are 100% open source,
According to the DB-Engines website, Apache Solr, is the second most popular search engine software in use today. Since Solr is written in Java, performance will obviously be impacted by which JVM you use. Recently, here at Azul we decided to compare the performance of Solr running on Zing using C4 to Oracle’s Hotspot JVM
Here at Azul, our primary focus is on figuring out how to make the Java Virtual Machine (JVM) as fast as possible. If you look at what the JVM does for Java application code there are three main areas of functionality, all of which affect the performance of applications: Memory management (including the Garbage Collector)
Developing with Zing: Overview Azul gets asked frequently whether Zing–which is a by design a great production JVM on the server–would also satisfy a developer use case for Java applications. Typically, this means putting Zing onto a laptop or desktop and running developer IDEs and tools. Fortunately, several factors are converging to make Zing in
Earlier this week, I delivered a webinar entitled, “The Future of Garbage Collection in Java”. The premise of this session was to look at how things will change from a GC perspective in JDK 9 and then look a little further into the future at what research is being conducted in this area (specifically project
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
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
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,
One of the things I love about my job is the fact that I get to meet developers from all over the world. A while back I sat down and figured out that, during my career, I’ve spoken about Java to audiences in 57 countries (and I’m always looking for new places to go).
This week we had one of the three face-to-face meetings that the JCP executive committee (EC) has each year. This is only my second meeting of this format; despite my long history with Java it’s interesting to see the way things work from this perspective. Since the minutes of the meeting have not yet
