The HotSpot Java Virtual Machine is written in C++(this is the leading edge, high performance replacement for Sun's"classic JVM" which was written in C).
It is integrated into the Java Virtual Machine(JVM) and causes almost no performance overhead, so it can be used even in heavily loaded production environments.
The Java SE Runtime Environment contains the Java virtual machine, runtime class libraries, and Java application launcher that are necessary to run programs written in the Java programming language.

The application in the background following the work of running programs running on the Java virtual machine(JVM), thereby effectively distributes resources RAM, ensuring maximum productivity performance of your….
This allows the Java Virtual Machine and other aspects of the application server to be monitored or managed remotely by third-party systems management software that complies with JMX such as Zabbix or HP OpenView.
Important: The Java virtual machine(JVM) of the application server needs read and execute privileges on the copied native and Java libraries. Both copied files must also be readable and executable at least for the application server process in your operating system.
Fortunately, most of the Java Virtual Machine remains unchanged since then, so by the time the reader discovers a detail that's different from JDK 1.2, they will be ready to leave the book behind and move on to the next topic.
Comprehensive monitoring and management support for Java platform including Monitoring and Management API for Java virtual machine, Monitoring and Management API for the Logging Facility, jconsole and other monitoring utilities, out-of-the-box monitoring and management, Java Management Extensions(JMX), and Sun's Platform Extension.
As part of that change, IBM decided to contribute the Java Virtual Machine(JVM) technology that it's used on the IBM i(and other platforms) for the last 12 years to the open source community.
Note: Ensure that the Java virtual machine(JVM) of the application server has both read and execute privileges on the native library. On Windows, the following exception appears in the application server log if the JVM of the application server does not have the executable rights on the copied native library.
