Mirza Aliev updated IGNITE-13306:
---------------------------------
Description:
Start cluster under Java 11.
Observed:
CpuLoad metric will return -1
Expected:
Real CpuLoad.
We investigated this issue and found that under Java 11 code failed with
following trace:

Under Java 8 metric has expected value.
Solution:
The behaviour is expected because in Java 11 the CPU load metrics is moved to
JDK internal module which is not accessible by default. Adding the following
line to the jvm in which Ignite node is started should solve the issue:
--add-opens jdk.management/com.sun.management.internal=ALL-UNNAMED
