Issue Description
JDK-8234484

Added Ability to Configure Third Port for Remote JMX


JMX supports (explicit) remote network access through the configuration of two network ports (either from the command line or in a property file), by setting the following properties:

com.sun.management.jmxremote.port=<port#>
com.sun.management.jmxremote.rmi.port=<port#>

Note: If it is not specified, the second port will default to the first.

A third local port is also opened to accept (local) JMX connections. This port previously had its number selected at random, which could cause port collisions.

However, it is now possible to configure the third JMX port (local only) by using:
com.sun.management.jmxremote.local.port=<port#>

Cgroups v2: Container awareness


The HotSpot runtime code as well as the core libraries code in the JDK has been updated in order to detect a cgroup v2 host system when running OpenJDK within a Linux container.

Since the 8u202 release of OpenJDK, the container detection code recognized cgroup v1 (legacy) host Linux systems. With 8u372 and later releases, both versions of the underlying cgroups pseudo filesystem will be detected and corresponding container limits applied to the OpenJDK runtime.

Without this enhancement, OpenJDK would not apply container resource limits when running on a cgroup v2 Linux host system, but would use the underlying hosts' resource limits instead.

Added Certigna(Dhimyotis) CA Certificate


The following root certificate has been added to the cacerts truststore: ` + Certigna (Dhimyotis) + certignaca DN: CN=Certigna, O=Dhimyotis, C=FR `
