The REPL process dies without Calva ”noticing” it when using one JDK (but works with another JDK)
- VSCode version: 1.68
- Calva version: 2.0.286
- OS: MacOS Monterey 12.4 M1 Chip
While the command seems to be executing, (e.g. it will show an error if u are not connected to the repl at all) After the evaluation is completed the result is not being shown anywhere. Nor in the REPL/Output window, nor inline in the editor. Initially i thought the problem was with my project setup, but the default calva tutorial has the same problem
Hi!
I'm not quite following. Can you describe the steps you take to get to the error?
Afaik we do not show an error if you evaluate forms without a REPL connected. We instead show some options for connecting a REPL.
- Open default calva tutorial via Calva: Fire up the Gettings Started REPL
- Follow the tutorial, place the cursor anywhere on the 3rd line and press the keybinding.
- Nothing happens E.R. The output is showed somewhere
If u try to evaluate a form without a repl connection the error message in the right bottom corner appears
Btw, trying to evaluate a line in the REPL leads to noting as well. Only the "evaluated" form is highlighted a bit but no actual output is being shown. Nor side effects (like printing)
Can you try with using the commands from the command palette and see if that makes a difference? So, instead of using the keybindings, bring up the command palette and execute a command like Calva: Evaluate Top Level Form (defun).
I can't reproduce this. @SonyaHon Can you paste the output from the dev console after you reproduce the issue? Help -> Toggle Developer Tools -> Console Tab.

Some interesting thing there is that Unhadled error n.trim is not a function is thrown only once. Futher tries to eval a form do not trigger this error
Oh wow. @PEZ Maybe something with OpenJDK 18 doesn't play well with Calva, at least with regard to the getting started repl?
@SonyaHon Did you kill the jack-in process yourself? It looks like something caused it to be killed, which would explain why you couldn't evaluate any forms.

Nope. I did not kill it. And there was a REPL Connected thingy in the bottom bar of VSCode. As i already sad, this problem exists not only in getting started repl, but everywhere.
I guess we should consider this closed as the issue is caused by me using OpenJDK 18. Switching to OpenJDK 11 fixed the problem.
Thanks for the info. @PEZ Do you want to leave this open under this new name and maybe investigate further later, or close it?
I think we should keep it open. But we need another name, because JDK 18 isn't the problem. I use OpenJDK 18 as my default JDK and it works great.
% java --version
openjdk 18.0.1 2022-04-19

@SonyaHon do you remember how you installed OpenJDK 18 on your machine? And what's the value of $JAVA_HOME on your machine? Thinking that if it is pointing somewhere else than JDK 18 when you are using that, maybe that can cause the issues. (My knowledge about how the JDK/JVM is bootstrapped is very limited, so I am just guessing stuff here.)
Don't know if the name I choose now is very good, but I tried to capture what I think is the Calva issue here. We can't do very much about a JDK that isn't properly configured, but Calva keeps indicating that things are good even though the REPL has died. That's at least actionable. (Even though I really don't understand why it glitches.)
Iv installed both 18 and 11 via brew. $JAVA_HOME is empty. The 18 version is used via PATH to java elf, than i created and alias java=path/to/java11 elf.
Closing this as we have no real clues what we can do about it. If someone finds more clues and also finds this issue, please reopen.
