Question

I am also getting the error `ScriptEngineManager providers next javax script ScriptEngineFactory Provider org jetbrains kotlin mainKts jsr223 KotlinJsr223MainKtsScriptEngineFactory could not be instantiated` in the kernel output which is fairly vague Is there a way to get a more concrete error

Ilya Muradyan · Answer

Could you please share a small repro project It is very likely to be a classpath shadowing issue but I don t fully understand how you are trying to use kernel code

Florian Magin · Answer

Ok I will do that Is just the code enough for you or do you need to be able to run the project to test it yourself The latter requires a bit more work on my side because my setup for the actual application is also somewhat hacked together

Ilya Muradyan · Answer

I want to see your Gradle Maven configuration Runnability will be a good option

Ilya Muradyan · Answer

Thanks

Florian Magin · Answer

Will probably only get around to cleaning this up tomorrow but I think reducing it to a minimal example that reproduces my expectations should already be helpful for me to understand it Will poke you when I am done slightly smiling face

Florian Magin · Answer

I have a minimal setup to illustrate what I would like to support any preferred way to share

Ilya Muradyan · Answer

Nice I think Github will be OK maybe private repo if you wish My nickname is `ileasile`

Florian Magin · Answer

ok you got an invite

Florian Magin · Answer

there are some leftover code snippets that aren t necessary but I think the README should describe everything relevant to reproduce the behavior I would like to change

Ilya Muradyan · Answer

Got your invite thanks I ll look at it

I am digging through the kotlin jupyter right now and I think I have an idea why this is happening if I understand this correctly The static variables are only set on the class in the context of a specific class loader and the jupyter kernel uses a separate class loader

Florian Magin · Answer

I am talking specifically about the code here <https github com Kotlin kotlin jupyter blob 41759064af9c4d3dd0be09f55f64fe4a742fea4f src main kotlin org jetbrains kotlin jupyter repl kt L317 L327>

Florian Magin · Answer

The repo I sent you is obsolete now it was the issue with the class loader after all I created the PR and would like to discuss merging these or other changes to accommodate this use case

Ilya Muradyan · Answer

Ok I ll look at this PR later Thanks slightly smiling face

Florian Magin · Answer

Thank you for your help so far slightly smiling face The first PoC for what I wanted already works quite well The actual PR is just ~5 10 lines changed in total but I have no idea if this is the proper way to do it

Florian Magin · Answer

I am currently refactoring this and finding more and more things that will absolutely come back to bite me if I don t do it properly now So I am still thankful if you checkout the PR later to get a general idea of what I am doing but I am now fairly sure that the current version is not something I actually want to be merged sweat smile
