When karaf app with this setting:

cpuRequest=500m
cpuLimit=500m
memoryRequest=256Mi
memoryLimit=256Mi

is deployed then this error occur

Executing /deployments/karaf/bin/karaf server ...
CICompilerCount of 1 is invalid; must be at least 2
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

If memoryRequest and memoryLimit are higher (eg. 512Mi) then it works (-XX:CICompilerCount=2 is set correctly). There must be some condition which with lower memory doesn't set the CICompilerCount to correct value.
