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

Hi,

could I get reviews for this small patch? bug: https://bugs.openjdk.java.net/browse/JDK-8034775 webrev: http://cr.openjdk.java.net/~anoll/8034775/webrev.00/ With this patch, we check at VM startup for a reasonable minimal number of compiler threads (1 for non-tiered, and 2 for tiered). If this minimum is not reached, the VM exits. Added regression test. Many thanks, Albert
