Procyon is a suite of Java metaprogramming libraries offering a rich reflection API inspired by .NET's System.Reflection, a LINQ-style expression tree API for runtime code generation, and an experimental Java decompiler. It is published on Maven Central as a set of JVM libraries.

Use cases

• decompile java class files to readable source
• inspect generic types with a rich reflection api
• generate java bytecode at runtime
• build expression trees that compile to callbacks
• analyze compiled java code programmatically

When to choose

• you need better generics introspection than core Java reflection provides
• you want declarative expression-tree-based runtime code generation on the JVM
• you need a Java decompiler for reverse engineering or analysis

When to avoid

• you need actively maintained tooling with frequent updates
• you want a stable, non-experimental decompiler for production pipelines
• you are not working on the JVM or with Java bytecode
