Source: isorelax
Version: 20041111-11
Severity: serious

Hey,

Rebuilding isorelax fails to build with:
javadoc: error - The code being documented uses packages in the unnamed module, but the packages defined in /usr/share/doc/default-jdk-doc/api/ are in named modules.

The reproducible build logs show a similar error:
