[SOLVED] /usr/lib/jvm/java-20-openjdk/lib/modules timestamp changed

Whenever I run 'java --version', I get this output:

$ java --version 

Output:

[0.006s][warning][cds] A jar file is not the one used while building the shared archive file: /usr/lib/jvm/java-20-openjdk/lib/modules
[0.006s][warning][cds] /usr/lib/jvm/java-20-openjdk/lib/modules timestamp has changed.
openjdk 20.0.1 2023-04-18
OpenJDK Runtime Environment (build 20.0.1+9)
OpenJDK 64-Bit Server VM (build 20.0.1+9, mixed mode)

What does the first two lines of the output signifies? Is it normal or do i need to fix something?

Thanks in advance.

I have the same issue.
I download openjdk archive from site jdk.java.net/20/
Extract and then replace original lib folder with extracted lib folder, and this warning is gone away.

Just updated my packages and have the same behavior when starting jar applications from cli.

Here also, still digging for an answer, will post back if I figure it out.

Stupidly, I completely missed this response earlier. Can confirm this has worked for me, thanks @Viterzgir.

OK, but this is not we way we're supposed to do this longterm right? The package will eventually be updated, I hope.

Just FYI I opened a bug to track this issue https://bugs.archlinux.org/task/78279

This solution basically boils down to discarding the package provided binaries and manually installing them.
A more clean approach is to just install them with the corresponding AUR https://aur.archlinux.org/packages/java-openjdk-bin

My personal preference is temurin though https://aur.archlinux.org/packages/jdk-temurin, OpenJDK binaries aren't a great choice to be honest. More info here https://whichjdk.com/
