Building Native Executables

The project supports building native executables using GraalVM. This creates a standalone binary with faster startup time and lower memory footprint.

Prerequisites

1. Install GraalVM (recommended: GraalVM 22.3 or later)
2. Set GRAALVM_HOME or JAVA_HOME to point to your GraalVM installation
3. Install the native-image tool:

   gu install native-image

Build Native Executable

To build a native executable, run:

./mvnw clean package -Pnative

The native executable will be created in target/jvm (or target/jvm.exe on Windows).
