Good old Java is also stable and yet popular. It is not particular "trendy", thought. My feeling is that languages which "live in"/"create" ecosystems such as JVM, BEAM or even LLVM have a better probability to outlive other languages in the long run. Let's see what happens with golang in some years... ;-)
Stable? Huh. Never thought of Java that way. Dead, yes, but it was never stable. In my experience I have to set up a custom JVM version for every java application I've come across. Is your experience different?
For me, Java died with Oracle shenanigans. I moved to C#. Java isn't truly dead yet but I think it will slowly die off because of Oracle. Same as Solaris and SPARC, but a little slower.
