This failure was caused by invoking the test case:
    testCpuShares(4096, 4);
    Set --cpu-shares to 4096, expect active processor count to be 4, actual is 2.


========== LOG

========== NEW TEST CASE:      test cpu shares, shares = 4096
[COMMAND]
docker run --tty=true --rm --cpu-shares=4096 jdk-internal:test-cpu /jdk/bin/java -Xlog:os+container=trace -version
