Since version 9, Java has new features every 6 months and it’s very hard to keep track of these new changes. Most of the information on the internet describes changes between the last 2 Java versions. However, if you’re in a similar situation as me, you’re not using the last Java version but a version several releases older.

As a Java EE developer, I sometimes envy how fast it’s possible to see the result of a code change in a running application with interpreted languages like PHP or JavaScript. With Java, it’s always necessary to rebuild the source code in a bytecode, which can be then safely updated only by restarting the whole application. And all developers know that restoring the desired state of the application after a fresh restart takes time and is tedious. A while ago I’ve come across an opensource tool called HotswapAgent that speeds up code reloading. (more…)

Well, not yet…but they announced to shutdown java.net and kenai by May 2017. I have been interviewed about this for an ADTmag article The ‘Sunsetting’ of Kenai and java.net

As Oracle provided little information to what will happen to critical projects that are already hosted on java.net, most of what was written in the article is still valid. Therefore I’m reposting my comments here again.

Anybody I don’t like, read this! :

com.superframework.core.base.Object object = new com.superframework.core.base.Object()

Sometimes one cannot avoid this rubbish in Java, even today. I do not wish my enemies to read such code, not in my code I want to be proud of!

I wonder how many times I have asked myself why Java is so complicated to read and write? Why I have to keep writing so many characters and lines of code to express a simple repetitive task? It’s appeared to me like Java language designers keep torturing developers by forcing us to use constructs invented 15+ years ago without an alternative.

But this one is simply an outrage. (more…)
