 # Native JShell and Espresso: Mixing AOT and JIT for Java
 
-This demo showcases the integration between [GraalVM Native Image](https://www.graalvm.org/reference-manual/native-image/) and [Java-on-Truffle (Espresso)](https://www.graalvm.org/reference-manual/java-on-truffle/).  
-It builds a native executable version of `jshell`, that executes the dynamically generated bytecodes on Espresso. This hybrid mode achieves instant startup, beating the vanilla `jshell` in both: time to the first interaction and time to evaluate a simple expression.

 JShell is a Java read-eval-print loop tool first introduced in Java 9, this demo also allows running `jshell` on Java 8.
