Broken redirect for IBM Semeru Open JDK 25 (OpenJ9) - package points to wrong GitHub release

[LikeTheSalad]

Description

The disco API package 97f7013bf7d5f5f57872e01936c58bfb (ibm-semeru-open-jdk_x64_linux_25.0.2.1.tar.gz, distribution: semeru) has a redirect URL that points to the wrong GitHub release, resulting in a 404 when Gradle attempts to download the toolchain.

Steps to reproduce

1. Query the package:

   GET https://api.foojay.io/disco/v3.0/ids/97f7013bf7d5f5f57872e01936c58bfb
   

2. Follow the redirect:

   GET https://api.foojay.io/disco/v3.0/ids/97f7013bf7d5f5f57872e01936c58bfb/redirect
   

3. The redirect resolves to:

   https://github.com/ibmruntimes/semeru25-binaries/releases/download/jdk-25.0.2%2B10_openj9-0.57.0/ibm-semeru-open-jdk_x64_linux_25.0.2.1.tar.gz
   

4. This URL returns HTTP 404 because the file ibm-semeru-open-jdk_x64_linux_25.0.2.1.tar.gz does not exist in the jdk-25.0.2+10_openj9-0.57.0 release.

Root cause

IBM published a newer release jdk-25.0.2+10.1_openj9-0.57.0 (on Feb 25, 2026) which contains the file ibm-semeru-open-jdk_x64_linux_25.0.2.1.tar.gz. However, the disco API redirect still points to the older release tag jdk-25.0.2+10_openj9-0.57.0, which only contains files named with the old convention (e.g., ibm-semeru-open-jdk_x64_linux_25.0.2_10_openj9-0.57.0.tar.gz).

The correct redirect should point to:

https://github.com/ibmruntimes/semeru25-binaries/releases/download/jdk-25.0.2%2B10.1_openj9-0.57.0/ibm-semeru-open-jdk_x64_linux_25.0.2.1.tar.gz

Impact

This breaks Gradle toolchain auto-provisioning for anyone requesting {languageVersion=25, implementation=J9}. The error seen in CI is:

Cannot find a Java installation on your machine matching: {languageVersion=25, vendor=any vendor, implementation=J9, nativeImageCapable=false}.
Some toolchain resolvers had provisioning failures: foojay (Unable to download toolchain matching the requirements
from 'https://api.foojay.io/disco/v3.0/ids/97f7013bf7d5f5f57872e01936c58bfb/redirect',
due to: Could not read '...' as it does not exist.)

This likely affects all Semeru packages for the 25.0.2.1 version, not just the x64_linux JDK.

Yep saw that too, thanks for the heads up, will look into it today 👍🏻
