just for the record, [the job](https://openj9-jenkins.osuosl.org/job/systemtest.getDependency/49/) was fine on Oct 27, 2024.

Start with the linked systemtest.getDependency/50 Jenkins console and openJDK.test.mauve/build.xml lines 380-390, then compare with job 49 from October 27, 2024. Investigate the missing .cvspass and connection failure to sourceware.org:2401; done means the Mauve source can be retrieved and the listed pull requests can be verified.
