## What it is
GraalVM is a high-performance JDK distribution that includes an advanced just-in-time compiler and Native Image, which compiles Java applications ahead of time into standalone native executables. It also provides the Truffle framework for building high-performance language interpreters, enabling polyglot execution of languages like JavaScript, Python, and Ruby on the JVM.

## Use cases
- compile java applications to native executables with fast startup
- reduce memory and cpu usage of java microservices
- build cloud-native java apps for serverless and containers
- implement custom programming languages on the jvm
- run multiple languages in one polyglot runtime
- improve java application security with smaller attack surface

## When to choose
- you need instant startup and low memory footprint for Java services or serverless functions
- you want to deploy compact native binaries in minimal container images
- you are building a language interpreter or polyglot runtime on the JVM
- you use frameworks like Spring Boot, Quarkus, Micronaut, or Helidon with native compilation support

## When to avoid
- your application relies on dynamic features incompatible with ahead-of-time compilation without extra configuration
- you need long-running batch workloads where JIT warmup is irrelevant and native image may reduce peak throughput
- you require strict open-source licensing, since Oracle GraalVM uses the GFTC license (Community Edition is GPLv2 with Classpath Exception)
- you depend on libraries using unsupported reflection, dynamic proxies, or JNI without reachability metadata
