Clerk doesn't load in java 22 #642
Comments
@qrthey thank you for reporting this! Graal has addressed the removal of sun.misc.Unsafe in java 22. I need to find a version of org.graalvm.js/js which uses the latest truffle api (nextjournal/markdown#23). |
I opened nextjournal/markdown#24 bumping Graal polyglot libraries to support Java 22, but we'll lose support for Java 16 and earlier, the oldest supported would be 17. |
@qrthey as a temporary workaround, to use Java 22 you might use nextjournal/markdown from github source as per io.github.nextjournal/markdown {:git/sha "6683c48dfdb23404a23057817b6ac3acf0310bca"} in your project deps.edn (you might need to exclude the jar dependency from clerk if clojure makes troubles resolving deps of different manifest types). |
Thanks @zampino . In my daily use of clerk, we are still on java 17. I just stumbled over this when trying some new java 22 stuff. In general I can see that it might be difficult to force users to upgrade to newer Java versions OR to have them not use the latest version. |
Confirmed that this works. I'm able to load Clerk with Java 22. |
Java 22 seems to have removed
sun.misc.Unsafe.ensureClassInitialized(java.lang.Class)
but it is required when loading thenextjournal.clerk
namespace (or one of its dependencies). The error specifies that the error occurs during compilation ofmarkdown.clj
.Local setup: Java 22, clojure 1.11.2, clerk 0.15.957 (arch linux, emacs cider 1.14, nREPL 1.1.1)
Can be reproduced by just having the Clerk dependency in deps.edn and evaluating following ns expression:
The documentation currently states that clerk should work on Java 11 and higher.
edit: Seems to originate from
org.graalvm.polyglot
used in https://github.com/nextjournal/markdown/blob/main/src/nextjournal/markdown.clj#L7 .The text was updated successfully, but these errors were encountered:
