My thoughts on Slackware, life and everything

Java SDK updates for Slackware all across the board

May 1, 2026 / / 1 Comment

Today I pushed fresh Slackware packages (for 15.0 and -current, and 32bit as well as 64bit) for various new OpenJDK releases. This is a quarterly process where the Java developers release a “GA” version. The “GA” stands for General Availability. The “GA” version indicates that the software is considered stable, feature-complete, and ready for use in production environments. It also marks the release of a new Icedtea framework which is still used to produce the openjdk and openjre (OpenJDK 8) package for Slackware. These are the JDK releases that I grab, compile and package for Slackware.

  • openjdk: updated to 8u492_b09, using the icedtea-3.39.0 framework.
    Note that for OpenJDK 8, you need to install either the JDK or the JRE, not both (the JDK package contains the JRE).
  • openjdk11: updated to 11.0.31_11.
  • openjdk17: updated to 17.0.19_10.
  • openjdk21: updated to 21.0.11_10.
  • openjdk25: updated to 25.0.3_9.
    The 32bit openjdk25 package contains the Zero JVM (which is not optimized for the architecture, because it contains zero assembly) thus this Java will be very slow. This is because other JVM’s are no longer supported on 32bit, starting with OpenJDK 25.

Get the packages from my server: http://slackware.nl/people/alien/slackbuilds/ or one of the main mirrors. In the US  that is my own http://us.slackware.nl/people/alien/slackbuilds/ and in the UK it’s Tadgy’s server at https://slackware.uk/people/alien/slackbuilds/ .

My advice has always been to: only install one version of Java!
However I need to make a footnote here. With OpenJDK 25 I made a fundamental change to the packaging process, The library files are installed into /usr/lib{,64}/jdk25 instead of the path /usr/lib{,64}/java that I have been using historically.
What this means is that starting with OpenJDK 25 packages, you can co-install multiple versions of the JDK. The /usr/lib{,64}/java is no longer a directory but a symlink and you can make it point to the OpenJDK version of your choice.

Let me know if I need to make the same change to future packages of OpenJDK 8 through 21.

Have fun! Eric

Java updates for 2024Q2

May 13, 2024 / / 7 Comments

Three weeks ago, the quarterly (security and stability) updates to various Java source code repositories were released. This means, new packages for OpenJDK versions 8, 11 and 17 are now in my Slackware repository. It took a while but hey, here they are.
For OpenJDK 8 I still use icedtea to compile the Java sources because it is convenient. The more modern versions like 11 and 17 are easier to compile (plus, icedtea does not support them).

All of these Java packages are nowadays targeting Slackware 15.0 and newer. So, get one of these if you have a need for it (and do not install more than one of them):

  • OpenJDK 8u412_b08 comes as an openjdk package.
  • OpenJDK 11.0.23_9 (aka the 11.0.23 General Availability release) comes as an openjdk11 package.
  • OpenJDK 17.0.11_9 (aka the 17.0.11 General Availability release) comes as an openjdk17 package.

Have fun!

Updates for Chromium (-ungoogled also), LibreOffice, Java

November 29, 2022 / / 16 Comments

Around the last weekend I worked on several package updates. In the meantime I had to battle home infrastructure breakdown, as well as the realization that I had inadvertantly opened up my SMTP server as an open relay and had to do some fast infrastructure redesign 🙁

Anyway:

Chromium, regular and ungoogled.

There was a new release at the end of last week. The Chromium 107.0.5304.121 release fixes a security issue for which an exploit already exists in the wild (CVE-2022-4135).
I provide packages for this release both for chromium and chromium-ungoogled. Target OS releases are Slackware 14.2 and higher (32bit and 64bit).

LibreOffice.

The latest release of LibreOffice ‘fresh’ is 7.4.3. This is an incremental bugfix release.
I provide packages for this release, targeting Slackware 15.0 and newer.
Note that my libreoffice package depends on openjdk11 (see below). If you are running slackware-current instead of 15.0, you will additionally need boost-compat and icu4c-compat packages to provide the libraries that are no longer present in -current.

Java.

Oracle released its quarterly update to the Java source code release affecting both JDK 8 and JDK 11.
Andrew Hughes provides an updated icedtea release to be able to compile OpenJDK 8 update 352 build 08. My openjdk package targets Slackware 14.2 and newer.
And for the OpenJDK 11.0.17_8 (aka the 11.0.17 General Availability release) update I provide an openjdk11 package which targets Slackware 15.0 and newer.

Have fun!

OpenJDK11 has been added to my repository

August 9, 2022 / / 13 Comments

For ages, I have had Java 7 and Java 8 packages in my repository. I compile these versions of Java from the OpenJDK sources and using the icedtea framework.

People have been asking about more recent versions of Java, in particular Java 11 and Java 17 are required more and more by software projects. So far, I have been hesitant, since icedtea still only supports Java 7 and 8. Writing a new build script from scratch is a lot of work and Java gives little reward.

Eventually, I have decided to build Java 11 packages regardless, main reason being that LibreOffice seems to need it to enable functionality in Base. Therefore expect the next update of my LibreOffice packages to have been compiled against OpenJDK11.

Note that I will not be creating separate JRE (Java Runtime Environment) packages. The JDK (Java Development Kit) is what you’ll get from me. It contains everything you need to compile and run Java programs. Don’t forget to logout and login again after installing openjdk11, since it installs a profile script which is sourced during login.

Packages are on slackware.com or on my NL or US mirror.

I took some inspiration from the SBo script maintained by Lenard Spencer, to save time, but in the end my script ended up quite different. I credited Lenard in my own script though.

$ java -version
openjdk version "11.0.16" 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8)
OpenJDK 64-Bit Server VM (build 11.0.16+8, mixed mode)
$ javac -version
javac 11.0.16

Now let’s see if I can stay op top of security updates… Andrew Hughes has been doing a stellar job of informing me about the icedtea releases that prompted me to update my openjdk/openjre packages.

October ’21 updates for OpenJDK 7 and 8

November 8, 2021 / / 2 Comments

icedteaThe newly released icedtea 2.6.28 and 3.21.0 build OpenJDK 7u321_b01 and OpenJDK 8u312_b07 respectively. These releases include the October 2021 security fixes for Java 7 and 8 from Oracle.

Here is where you can download the latest Slackware packages for openjdk7 and openjre7 (Slackware 14.1 and newer):

… and openjdk and openjre version 8 (Slackware 14.1 and newer):

Rsync access via rsync://slackware.nl/mirrors/people/alien/slackbuilds/

The “rhino” package (implementation of the JavaScript engine used by OpenJDK) is an external dependency for OpenJDK 7, you can find a package in my repository. If you want to compile OpenJDK yourself you will need apache-ant as well.

Note about usage:

My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.

Remember that I release packages for the JRE (runtime environment) and the JDK (development kit) simultaneously, but you only need to install one of the two. The JRE is sufficient if you only want to run Java programs (including Java web plugins). Only in case where you’d want to develop Java programs and need a Java compiler, you are in need of the JDK package.

Enjoy! Eric
