Last weekend I uploaded updates for OpenJDK based Java versions 8, 11 and 17, and added a new version 21 to the repository.
Specifically, my repository now offers:

  • openjdk (version 8): updated to 8u482_b08 for Slackware 15.0 and newer, using the icedtea 3.38.0 framework.
    Note: for OpenJDK 8, you need to install either the JDK or the JRE, not both (the JDK contains the JRE).
  • openjdk11: updated to 11.0.30_7.
  • openjdk17: updated to 17.0.18_8.
  • openjdk21: added 21.0.10_7.

All packages are for Slackware 15.0 and newer. Both 32bit and 64bit variants are offered.
Only install one version of Java!
