November has been a busy month, primarily because it seems that this is the most popular month to organise a European Java conference. I guess this makes sense as it’s just after JavaOne, so various new things to discuss and it’s not holiday season (Europe is untroubled by any form of Thanksgiving). It’s also late
Recently, I ran a webinar on “Migrating Applications to JDK 9” . To develop this, I used some of the material I had researched for an earlier blog post along with new material gleaned from different sources. Rather than looking at the details of moving an application from the classpath to a set of modules, I
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
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
You wait three and a half years for a JDK release and then three come along in the space of a year (thus the reference to buses in the title of this post). It’s now been officially proposed by Mark Reinhold, Chief Architect of the Java Platform Group at Oracle that the Core Java Platform
Azul often gets asked how to apply newer time zone definitions to already installed JDKs. Up until now, the answers have been: (1) update your JDK to the latest revision, which will have newer timezone details inside, or (2) download and use tzupdater. Since the answer for (2) is free but not always attractive, Azul
My apologies for severely misquoting Lao Tzu in the title of this blog post but it occurred to me today that we are only 16 days (10000 in binary, hence the title) from the release date of JDK 9. Hopefully, everyone who intends to use JDK 9 has downloaded an early access (EA) build
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 OpenJDK 9 here. Recently I’ve been doing a presentation
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)
