Graal is an Oracle project aiming to implement a high performance Java dynamic compiler and interpreter.[3][4]

The objective of Graal is to improve the performance of Java virtual machine-based languages to match the performance of native languages.[5]

Truffle

Associated with Graal, Oracle is also developing a language Abstract syntax tree interpreter called Truffle which would allow it to implement languages on top of the Graal framework.[6][7]

Ahead-of-Time Compilation

In September 2016, Oracle detailed plans to add ahead-of-time compilation to the OpenJDK using the Graal compiler for Java 9.[8][9] This proposal is tracked by the JEP 295: Ahead-of-Time Compilation, proposed for Java 9.[10]

The effort would explore implementing a dynamic compiler that can be used in a native JVM such as HotSpot or a metacircular JVM such as Maxine. On its project site, Oracle describes the Maxine VM as a next-generation platform written in Java, compatible with modern Java IDEs and the standard Java Development Kit, and featuring a modular architecture
