Module java.sql not found

[mvsrgc]

I tried to install this language server using Mason with JDK 19. When I did this the link_linux.sh script failed with "module java.sql not found". I upgraded to JDK 20 and that fixed the problem.

Same problem happening for me but for JDK17

Getting the same problem with OpenJDK 17 and OpenJDK 20, this is the error:

but the module seems to be there:

java --list-modules | grep java.sql@

java.sql@17.0.6

I'm running the latest (java 20) and getting the same error.

You have to install e.g. openjdk17-jmods (on Void Linux) or search for similar Java Modules package on your distribution.

Can confirm installing jmods fixes the issue with JDK 20 as well.

Can also confirm on Fedora 39, installing java-17-openjdk-jmods fixed the issue.
