FAQPage Schema

How do I fix ClassNotFoundException in GraalVM Native Image?▼

To fix ClassNotFoundException in GraalVM Native Image, you must configure the necessary reflection-config.json file to explicitly register classes for AOT compilation, ensuring dynamic class loading works correctly.

How do I configure reflection and proxy settings for GraalVM AOT compilation?▼

Configuring reflection and proxy settings for GraalVM AOT compilation involves generating and applying reflection-config.json and proxy-config.json files to define access permissions for native binary creation.

Can I run Java and JavaScript together using GraalVM polyglot runtime?▼

Yes, you can run Java and JavaScript together using GraalVM polyglot runtime capabilities, which facilitate seamless cross-language interoperability and multi-language execution within a single JVM environment.

What is GraalVM Native Image AOT compilation used for?▼

GraalVM Native Image AOT compilation is used for building optimized native executables from Java applications, achieving high performance and fast startup times by compiling code ahead of time.

Why does my Java application fail when building a native executable with GraalVM?▼

Your Java application might fail building a native executable with GraalVM because AOT compilation requires explicit configuration for dynamic features like reflection, resources, and proxies.
