   Analysis & Triage

   • Problem Identified: GenericVersionTest.testCompareUuidRandom generates 2,048 unseeded UUID.randomUUID() strings per test run, leading to non-deterministic test runs and potential flakiness in CI environments.
   • Affected Versions: Both 1.9.x and 2.0.x.
   • Plan to Fix:
     1. Seed the Random instance with a fixed seed (0x5EEDCAFEL) to ensure 100% reproducible test runs across all platforms.
     2. Verify ordering and sorting assertions against fixed pseudo-random sequences. (Targeted for 2.0.24 in PR Fix listener error swallowing (#1990), SyncContext double-close (#1992), and test flakiness (#1350) #2108)
