8367302: New test jdk/jfr/event/profiling/TestCPUTimeSampleQueueAutoSizes.java from JDK-8366082 is failing

[parttimenerd]

Hi all,

This pull request contains a backport of commit d27649fe from the openjdk/jdk repository.

The commit being backported was authored by Johannes Bechberger on 8 Oct 2025 and was reviewed by David Holmes and Andrei Pangin.

The backported is not clean, because I had to resolve the removal of a test-related method that is no longer used and the problem list removal is no longer needed (the test has not been problem listed in JDK 25).

Thanks!
