The failing tests for JDK25 (as of 94a17b9) are

2025-11-27T15:50:16.4693986Z Errored scenarios:
2025-11-27T15:50:16.4694558Z   features/jboss.container.openjdk/openjdk.feature:36  Check that only OpenJDK 25 is installed
2025-11-27T15:50:16.4695611Z   features/jboss.container.openjdk/openjdk.feature:94  Check that directories from other JDKs are not present (JDK25)

The tests detect JDK21 -- this is pulled in by maven-openjdk21, which will be replaced with maven-openjdk25 once it is available. This is a useful check that the test is working.
