Update JRE dependencies for debian trixie #2342
Conversation
…pend on headless anyway)
…prefers the first one) Not changing build-depends here because I'm not sure if building with jdk-17 would result in a binary that wants jre-17.
The debian policy [1] still mentions javaNN-runtime-headless, but since openjdk-17 the debian packages provide a versioned java-runtime-headless dependency, and in openjdk-25 (and openjdk-24) the javaNN variants were dropped [2]. Also given the package uses the `update-alternatives`-selected default java depending on specific jre versions won't help anyway if a sysadmin installs a different jre additionaly and selects it (and newer versions will be selected by default anyway).

Hi, thanks for your contribution! |

debian trixie comes (currently) with
openjdk-21-jre-headless(selected bydefault-jre-headless) oropenjdk-25-jre-headless, but notopenjdk-17-jre-headless(nor 11). I'm currently running (a small personal instance) withopenjdk-25-jre-headlessand it seems fine.(
openjdk-17-jre-headlessis still installed but not selected as/usr/bin/java, and apt is unhappy about "locally installed" packages.)Another options for the dependency list would be
default-jre-headless | java-runtime-headless (>= 17).default-jre-headlessis a real package that depends on the default JRE of a debian release, andjava-runtime-headlessis a (versioned) virtual package provided by allopenjdk*-jre-headlesspackages since version 17 - on trixie this should default to 21 but allow 25.openjdk-11-jre-headlessshould be usable on buster and bullseye via thedefault-jre-headlessin those dists, or you could append| openjdk-11-jre-headlessas final alternative (afaik the versionedjava-runtime-headless (>= ...)shouldn't acceptopenjdk-11-jre-headless, because it providesjava-runtime-headlessonly without a version).I don't think a versioned dependency on
default-jre-headless(e.g. likedefault-jre-headless (>=2:1.11)) would be a proper solution; if you want to make sure a recent enough java is installed (although that doesn't guarantee it is selected for/usr/bin/java) you should stick tojava-runtime-headless (>= 17).Similar names could be used for the build dependencies.
If you tell me what semantics you'd like in the dependencies I can adjust this PR (within the limits of what is reasonably possible with the debian packages).
