The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library.Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform.
The Java Development Kit (JDK) is a distribution of Java technology by Oracle Corporation.It implements the Java Language Specification (JLS) and the Java Virtual Machine Specification (JVMS) and provides the Standard Edition (SE) of the Java Application Programming Interface (API).
The higher optimization levels use special techniques such as escape analysis and partial redundancy elimination, or loop through certain optimization sequences more times. Although these techniques use more CPU and memory, the improved performance that is delivered by the optimizations can make the trade-off worthwhile.
OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). [2] It is the result of an effort Sun Microsystems began in 2006, four years before the company was acquired by Oracle Corporation.

GraalVM has its roots in the Maxine Virtual Machine project at Sun Microsystems Laboratories (now Oracle Labs).The project's goal was to write a Java virtual machine in Java itself to avoid the problems of developing in C++, particularly manual memory management, and benefit from meta-circular optimizations.
