Groovy and GraalVM

GraalVM is the new hot tool in the JVM ecosystem. It brings a bunch of new features, including creating native binaries from Java bytecode files to run startup programs without the overhead. It also applies to programs written in our favorite programming language - Groovy. In this quick intro, I will explain how to start compiling Groovy code to a native binary using GraalVM, what are the benefits and what kind of limitations we have to be aware of.

This presentation was prepared for GR8Conf EU 2019

168. Dynamic nature Dynamic nature In most cases Groovy dynamic idioms won’t compile with AOT, thus it is recommended to use static compilation instead.  
