Richard Whitehouse created CASSANDRA-14390:
----------------------------------------------
Summary: Cassandra's Debian package depends on java-X-jre which
requires GUI components
Key: CASSANDRA-14390
URL: https://issues.apache.org/jira/browse/CASSANDRA-14390
Project: Cassandra
Issue Type: Bug
Components: Packaging
Reporter: Richard Whitehouse
Cassandra can't be installed against a later version of the JRE without also
installing a bunch of GUI packages which aren't relevant on a server
installation.
e.g. Cassandra 3 can't be installed against a Java 9 JRE without also
installing GUI components.
This is because of the Debian package dependencies.
Cassandra 3+ depends on `openjdk-8-jre-headless | java-8-jre`.
Cassandra 2.x depends on `opendjk-7-jre-headless | java-8-jre`
`java-X-jre` is a metapackage which specifies a Java version compatible with
the given Java version that includes GUI components. It's supplied by
`openjdk-X-jre` - e.g. `java-8-jre` is supplied by `openjdk-8-jre` and
`openjdk-9-jre`.
In comparison, `java-X-jre-headless` is a metapackage which specifies a Java
version compatible with the given Java version but doesn't require GUI
components.It's supplied by `openjdk-X-jre-headless` - e.g.
`java-8-jre-headless` is supplied by `openjdk-8-jre-headless` and
`openjdk-9-jre-headless`.
Can Cassandra be changed to depend on `java-8-jre-headless` instead of
`java-8-jre`?
This affects all releases since Debian packaging was introduced according to
the commit logs.
