Obscure classloader problem in cider

[jdf-id-au]

Hi, thanks again for a brilliant library.

I'm scratching my head about this one.

Using Clojure 1.11.1, OpenJDK 17, macOS 14.2.1, this works fine:

$ clj -M:examples
user=> (load "e28_canvas")

But using the same tools via CIDER in emacs (cider-jack-in-clj specifying the :examples alias, and running cider-load-buffer within e28_canvas.clj) gives an error (condensed):

[nREPL] Starting server via /usr/local/bin/clojure -Sdeps \{\:deps\ \{nrepl/nrepl\ \{\:mvn/version\ \"1.0.0\"\}\ cider/cider-nrepl\ \{\:mvn/version\ \"0.44.0\"\}\}\ \:aliases\ \{\:cider/nrepl\ \{\:main-opts\ \[\"-m\"\ \"nrepl.cmdline\"\ \"--middleware\"\ \"\[cider.nrepl/cider-middleware\]\"\]\}\}\} -M:cider/nrepl:examples
Loading /path/to/cljfx/examples/e28_canvas.clj...
=> Exception in thread "JavaFX Application Thread" java.lang.NoClassDefFoundError: Could not initialize class javafx.scene.control.Slider

Sometimes it's Control rather than Slider. The exception originates from the call to create-props in create-composite-component in cljfx.composite.

This did not happen in the past, but I haven't been able to determine which change in which system component caused it!

Empirically the only difference betwen (System/getProperty "java.class.path") between the two is the presence of cider-related jars orchard, nrepl, logjam and cider-nrepl.

Is there an obvious way I can investigate this further?

I do observe this problem as well. One additional remark I can paste the first example from cljfx's readme into the cider repl and it works. If I evaluate the same code from a buffer it fails.

I was also able to get it going by running nrepl within my project, starting it on the command line, and using cider-connect-clj... 🧐

Browsing cider issues, there was this (closed; more as context than explanation)

Could you try launching JDK from emacs and the command line and checking if (System/getProperty "os.arch") returns different results?
