Scala Hello World: NoSuchMethodError: java.nio.ByteBuffer.clear

Question

When I try to compile a simple hello world program in Scala:

Hello.scala:

object Hello {
    def main(args: Array[String]): Unit = {
        println("hello world")
    }
}

with scalac Hello.scala. I get

error: java.lang.NoSuchMethodError: java.nio.ByteBuffer.clear()Ljava/nio/ByteBuffer;

on Ubuntu 18 with scalac version 2.11.12 and java version 1.8.0_181. Strangely, this same program will compile and run on macOS with scalac version 2.12.6 and java 1.8.0_111.

My two questions are: why does this happen? How can I fix this?

Thank you.

It shouldn't make any difference as it's platform independent, as long as you have all the required dependencies. — zenwraight, Aug 29 '18 at 21:58
@zenwraight Indeed. That's why I'm confused about this behavior. — Jon Deaton, Aug 29 '18 at 21:59
Looks like the same issue reported in this [SO link](https://stackoverflow.com/questions/50876388/scala-script-wont-run-on-ubuntu). — Leo C, Aug 29 '18 at 22:00
@LeoC That link suggests that upgrading to scala 2.12 solves the problem. Am I correct in therefore concluding that hello world only works on scala 2.12? — Jon Deaton, Aug 29 '18 at 22:02
No my doubt is you might be having java 8 and java 9 and that jar is being compiled using java 9 or something like that, that's why i asked do u have multiple java versions installed ? — zenwraight, Aug 29 '18 at 22:04
@zenwraight I am under the impression that I have only Java 8 installed. — Jon Deaton, Aug 29 '18 at 22:13
does your scala REPL load OK? I recommend re-installing scala and see if the problem persists. — emran, Aug 29 '18 at 23:54
@JonDeaton what is output when you check `javac -version` in command line? — emran, Aug 29 '18 at 23:56
Upgrade to Scala version 2.12.6. It should compile successfully. — Arun George, Oct 21 '18 at 15:47

With scala 2.11.12, I had to install openjdk version "10.0.2". This was done with the command openjdk-11-jdk-headless weirdly enough.

https://docs.scala-lang.org/overviews/jdk-compatibility/overview.html

I was getting the same error when running openjdk version 8.

I don't think the compatibility matrix alone explains it. I've expanded my answer in another similar question to explain the reason for the error: https://stackoverflow.com/a/51223234/5180989 – Helder Pereira Dec 06 '20 at 20:52
