Albert,

your test fails, if it runs on VM w/o Tiered. I'd recommend to add -XX:-TieredCompilation as an arg:

34 ProcessBuilder pb = ProcessTools.createJavaProcessBuilder("-XX:-TieredCompilation -XX:CICompilerCount=-1"); and change the check: 37 String expectedOutput = "CICompilerCount of -1 is invalid; must be at least 1"; Igor

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
