Java 9



Eliminating Java Update Confusion

It has become clear to me, having spoken to many developers at many different events and seen recent postings on sites like Reddit, that there is still a lot of confusion about how the JDK will be delivered and updated in the future.

Java’s Magic Sauce

Or should I say, Java’s Magic Source? If we go all the way back to JDK 1.0, there were 211 classes in the public API. Out of interest, I created a graph showing the growth in public classes over time. To extract my data I used the API documentation and copied the list of all…

No JDK 9 For Windows XP

In my last blog post, I discussed the use of jlink to build shrink-fit Java runtimes that only contain the modules you need for your application. As part of the research for this, I was looking at one of the options for jlink that allows you to select a virtual machine type, the idea being…

Crouching Duke, Hidden Java

  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)….
