Hi! Thanks for the report, I'll have a look.

vlaaad · Answer 2 · Thu Feb 20 2020 05:11:37 GMT+0800 (China Standard Time)

I can't reproduce it with various JDKs I tried, can you tell me where you obtained your JDK?

Note for self: here is a java -version you posted on reddit:

openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10)
OpenJDK 64-Bit Server VM (build 11.0.6+10, mixed mode)

tianshu · Answer 3 · Thu Feb 20 2020 05:41:59 GMT+0800 (China Standard Time)

The oracle jdk 13, open jdk 13 don't work neither.
Is com.sun.javafx.tk.Toolkit built-in with jdk?

vlaaad · Answer 4 · Thu Feb 20 2020 17:13:58 GMT+0800 (China Standard Time)

No, it's a part of JavaFX library, which should be brought in as an artifact on java 11 and beyond. It's internal, but it has been a part of JavaFX for a long time. Could it be that you have some kind of headless JDK that can't have desktop access?

tianshu · Answer 5 · Fri Feb 21 2020 01:43:25 GMT+0800 (China Standard Time)

maybe, It could be. I installed these versions through package manager in Arch Linux, even though it doesn't named as headless.

I'll post when I have more information.

Greetings!

I have a similar (the same?) issue, even though I use a different Java version. The most important part of the error message highlighted in bold:

Exception in thread "JavaFX Application Thread" java.lang.IllegalAccessError: class vlaaad.reveal.font$fn__220 (in unnamed module @0x71527bdf) cannot access class com.sun.javafx.tk.Toolkit (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.tk to unnamed module @0x71527bdf

at vlaaad.reveal.font$fn__220.invokeStatic(font.clj:26)

The Java I use is 18.0.1:


openjdk version "18.0.1" 2022-04-19
OpenJDK Runtime Environment Zulu18.30+11-CA (build 18.0.1+10)
OpenJDK 64-Bit Server VM Zulu18.30+11-CA (build 18.0.1+10, mixed mode, sharing)

Updated

I switched to Java 1.8 a few minutes ago:

openjdk version "1.8.0_332"
OpenJDK Runtime Environment (Zulu 8.62.0.19-CA-macosx) (build 1.8.0_332-b09)
OpenJDK 64-Bit Server VM (Zulu 8.62.0.19-CA-macosx) (build 25.332-b09, mixed mode)

Running the REPL from the command line works well:

clj -A:reveal
Clojure 1.11.1
user=> (require '[vlaaad.reveal :as r])
nil
user=> (r/tap-log)
nil
user=> (tap> (System/getProperties))
true
user=>

Running the REPL in the same way it should run from the Cursive works too:

clj -A:reveal -m vlaaad.reveal repl

However, it fails to run from Cursive. This is the configuration I have:

The error message I get is

Reflection warning, cljfx/jdk/fx/window.clj:9:3 - call to method setForceIntegerRenderScale on javafx.stage.Window can't be resolved (no such method).
Reflection warning, cljfx/jdk/fx/window.clj:9:3 - call to method setRenderScaleX on javafx.stage.Window can't be resolved (no such method).
Reflection warning, cljfx/jdk/fx/window.clj:9:3 - call to method setRenderScaleY on javafx.stage.Window can't be resolved (no such method).
Syntax error (IllegalArgumentException) compiling . at (cljfx/jdk/platform.clj:12:5).
No matching method startup found taking 1 args for class javafx.application.Platform

It seems something is wrong with Cursive, though I have no clue what.

vlaaad · Answer 7 · Fri Jun 10 2022 13:34:34 GMT+0800 (China Standard Time)

@manenko After switching the jdk from 11+ to 1.8 or back you need to clear clj cache — either by running it with -Sforce or by removing .cpcache directory.

I deleted the .cpcache but the problem with Cursive is still there. Anyway, It does not seem to be a problem with the REPL. It is either of asdf, Java installation or Cursive. I'll keep trying :-)

The REPL is great, by the way. I was looking for a more comprehensive replacement for clojure.inspector. One of the requirements is that the alternative must be capable of working with the remote REPLs and reveal seems to be exactly what I need. I just have to figure out how to make it work with my company's setup :-)

Having the same problem with JDK17 but not with 11.

Tested with clj -Sforce -Sdeps '{:deps {vlaaad/reveal {:mvn/version "1.3.273"}}}' -X vlaaad.reveal/repl outside of a clojure project.

Error on JDK17 with JavaFX17

@lycheese "module javafx.graphics does not export com.sun.javafx.tk to unnamed module @0x48c59476" probably means jdk 17 is more restrictive about reflective access to internal classes. You'll probably need to add something like --add-opens=???/???=ALL-UNNAMED to the jvm args. I'm not sure what exactly should be there, I'll check when I return from the vacation

I think it should be -J--add-opens javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED (taken form this SO question) but it complains that modules need to be specified and I have been unable to get that working so far.

Elia Nolz · Answer 12 · Sat Jul 23 2022 04:22:23 GMT+0800 (China Standard Time)

Changing -J--add-opens javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED to -J--add-opens -Jjavafx.graphics/com.sun.javafx.tk=ALL-UNNAMED did it.

Edit:

Full working command for javafx17:

clj -J--add-opens -Jjavafx.graphics/com.sun.javafx.tk=ALL-UNNAMED -Sdeps '{:deps {vlaaad/reveal {:mvn/version "1.3.273"}}}' -X vlaaad.reveal/repl

If using :jvm-opts in deps.edn the two parts need to be two separate strings as well:

{,,,
 :jvm-opts ["--add-opens" "javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED"]
 ,,,}
