Both in github runner and AdoptOpenjdk:

@lumpfish @Mesbah-Alam any idea?

Run TestJlmRemoteMemoryAuth_0 with HotSpot JDK 8 on macOS and review the linked runner logs. Start at MemoryData.checkPeakAndCurrentMemoryUsage and follow its call path from MemoryProfiler.getStatsViaServer, focusing on the Code Cache peak and current values. Done means the test completes with the expected exit code 0 on the affected environments.
