Java 20 is in dev, and though "20" is an arbitrary mark rather than anything special, I decided to review where Java is. This time I started with the JVM landscape and immediately wondered why there are so many JVM organizations. One answer is that there are around 30 million software developers in the world (almost all estimates place it somewhere over 25 million). 10 million of these (approximately) program Java, though it's not clear how many have Java as their primary language.

Going back to the large number of JVMs available - at least 10 different major organizations each providing their own freely available JVM, with support - I think you need a huge base of JVM users to support so many. So this is the answer for me, a huge base of Java developers means the JVM landscape can flourish.

Add to the extensive projects available and so many major websites running on Java, and all this shows Java continues to be amazingly successful! Now on to all the usual newsletter list of links, tips, tools, news and articles, and as usual I've extracted all the tips into this month's tips page
