RFR(XXS): 8034775: Failing to initialize VM when running with negative value for -XX:CICompilerCount

[Vladimir Kozlov]

Albert,

Can you also check upper limit: os::active_processor_count()?
Tiered works when CICompilerCount=1. Can you look what is difference in such case from CICompilerCount=2?

The test expects "at least 2" but for Client VM and non-Tiered it is 1. So your test will fail.

Thanks,
Vladimir
