Developers Finally Moving Away from Java 8 to Java 11 (sdtimes.com) 61

Posted by EditorDavid from the Java-everywhere dept.
SD Times takes another look at the uptake of Java 11 Previous reports of the Java community found that developers were still mainly using Java 8 and didn't adopt newer versions, but according to Snyk's JVM Ecosystem Report 2021, that is starting to change. This year, 61.5% of respondents are using Java 11 somewhere in production, and almost 12% are using the latest release, which was Java 15 during the survey. "This is huge, because it shows that developers do upgrade their Java version beyond Java 8 to some extent. The mantra that most Java developers are comfortable staying on Java 8 seems to be slowly breaking apart," Snyk stated in the report.

However, half of the Java 11 users — which is currently the most used version — still use Java 8 in their production stack...

In addition, almost half of developers (44%) use the free AdoptOpenJDK distribution in production as one of their JDKs and 48% use it in development.
"Other findings are that Java is still by far the most popular language by a long shot and Snyk stated it will probably remain that way in the foreseeable future and that JetBrains IntellIJ IDEA still remains dominant as an IDE in the Java ecosystem."

      The difference between Java 8 and Java 11 isn't that huge from the majority of the code base so there's no real need to enforce an upgrade.

      The most recent important update of the language was the introduction of generics. Subsequent updates haven't been as important even though they have been interesting for some cases.

    This is a good example of Version number creep. Why does Java need "a version number" , can't they make a Java "just work" ?

    Clearly not. I remember this with 1.1 when people were still on 1.0.2 and it was like ... why is stuff breaking?

    This is what ultimately is going to be the death of Java and it being replaced by something that is stable.

    There are depreciated things in C and C++ but that's largely at the suggestion of the compiler, when microsoft started calling non _s functions depreciated, 3+ versions of MSVC ago. Yet if Microsoft actually removed that functionality, then everyone would have to use Clang, which hasn't.

    Rather C/C++/OBJC have the reverse problem where developers do not use exotic features of the language, and are discouraged from doing so if the program is intended to be portable. If your code can't compile on the C99/C++98, then it's not portable enough for all platforms but you might get away with it if it compiles with Clang which is available on all platforms.

    Java on the other hand, just breaks, and there's no guarantee that a Java runtime will be on a system.

      If both Java developers and C++ developers tend to use older versions, how is that "the reverse problem"? No, it's the exact same problem, with developers only slowly taking up new versions.

      That's certainly not going to be the death of Java. As long as new updates are available buy older stuff can still be used, that's the normal way for a language to move forward.

      • But that wasn't really his point now was it. You can compile C89 code with your brand new C17 compiler and it just works. Python and PHP have the very same problems that Java have with every new version not building on the previous one but instead rewrites the language so code have to be ported.
