Package: diffoscope Version: 118 Severity: normal Hi,
Starting with the version 9 and the new module system OpenJDK has .jmod files containing compiled classes and resources. This file format isn't supported by diffoscope yet. It's basically a ZIP file but with an extra 4 bytes header: the "JM" string followed by 01 and 00 (the format version 1.0 I guess), so the first bytes are "4A 4D 01 00", immediately followed by the usual ZIP header "50 4B 03 04". Could you please implement this new container format? That would greatly help analyzing the reproducibility issues in OpenJDK 9 and later. The jmod files can be found in the openjdk-11-jdk and openjdk-12-jdk packages. You can test the implementation with: diffoscope /usr/lib/jvm/java-11-openjdk-amd64/jmods/java.management.jmod /usr/lib/jvm/java-12-openjdk-amd64/jmods/java.management.jmod Thank you, Emmanuel Bourg _______________________________________________ Reproducible-builds mailing list Reproducible-builds@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/reproducible-builds
