GraalVM和Jvm-Hotspot之间的区别

Question

有人可以解释GraalVM和Jvm-Hotspot之间的区别，以及GraalVM与OpenJDK的HotSpot有何关联。

Answer 1

在这种情况下，您可以将GraalVM视为经过修改/改进的HotSpot JVM [非常宽松：OpenJDK的HotSpot + Graal JIT编译器（从HotSpot取代了它）和运行其他语言（JS，Ruby，R， Python等）+能够AOT编译Java  +其他捆绑工具等]

Answer 3

GraalVM is a JVM with multiple change:

• the graal compiler. It is intended to replace the C2 compiler (server mode) in front of HotSpot.
• Truffle a library that you can implements to make JVM polyglot ( there already a number of language that are supported like js, R, Ruby...)

The graal project also have a Substrate VM which is a framework to build native artifact from Java.
