LF Graph cannot load via VS Code

zoey1124 commented 2 years ago

I am trying to go through LF mini-examples in this repo through my local VS Code IDE. I installed the Lingua Franca for VS Code in VS Code Market space, then I try to run the .lf file following the instructions. But there is an error for Java to compile and run, here is the error message:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/lflang/diagram/lsp/LanguageDiagramServer has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

My operating system is macOS with version 12.4 running on Apple M1 chip. My Java version is

$ java -version
java version "1.8.0_341"
Java(TM) SE Runtime Environment (build 1.8.0_341-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.341-b10, mixed mode)

Any suggestions about how should I proceed here?

You're using Java 8. Install Java 17, and you should be good to go.

zoey1124 commented 2 years ago

Now I've upgraded to Java 17

$ java -version
openjdk version "17.0.4" 2022-07-19
OpenJDK Runtime Environment Homebrew (build 17.0.4+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.4+0, mixed mode, sharing)

When I run CarBrake.if, it compiles successfully. However, it will throw the runtime error

We have known bugs with Mac when using diagrams (#27), and the upcoming release may resolve them in the next few days. I know very little about how to fix these issues because they seem to be related to the use of Gson as a transitive dependency via KLighD. (The stack trace posted above looks very abbreviated, so let me know if it is different from what I think.)

Shaokai had a very similar issue at some point, but I do not remember if/how he resolved it. Do you remember, @lsk567?

Just so that we have everything in one place, this was Shaokai's stack trace:

zoey1124 commented 2 years ago

I think I have the exactly same error message.

zoey1124 commented 2 years ago

I am now able to run some part of the examples, some other fails as #27 mentions

zoey1124 commented 2 years ago

I can run all examples for now. Problems solved. All I did actually is install Java 17 and reboot everything.
