The record

What it does: Spoon is an open-source library for analyzing, rewriting, transforming, and transpiling Java source code through an abstract syntax tree (AST).
Java support: The site says Spoon supports modern Java versions up to Java 25.
License: Spoon is free and open source under the CeCILL-C and MIT licenses.
Analysis: Spoon supports source-level static code analysis using processors that inspect AST elements of a selected type.
Code transformation: Spoon can transform source code, including for instrumentation and refactoring.
Architecture checks: The documentation describes expressing architectural rules as AST analysis and running them as JUnit tests in continuous integration.
Reflection: Spoon can act as an alternative to Java reflection and allows shared analysis of binary and source code through CtClass objects.
Parallel processing: Spoon provides an AbstractParallelProcessor API for running processors in parallel, with the documentation advising against using more parallel processors than available cores.
Install options: The documentation describes using Spoon from Java, the command line, Maven, or Gradle, and downloading its dependency jar from Maven Central for command-line use.
Java runtime requirements: Spoon 11.x requires JDK 17 or later, Spoon 10.x requires JDK 11 or later, and Spoon 9.x requires Java 8.
Command-line limitation: When using Spoon from the command line, users handle the classpath manually and should specify dependencies of analyzed source files with --source-classpath.
Semantic patching: The spoon-smpl submodule is described as a prototype implementation of a subset of Semantic Patch Language for a subset of Java.
Support: The site directs users seeking professional development, training, or extension support to comment on a GitHub issue.
Project affiliation: The site identifies Spoon as an official Inria open-source project and a member of the OW2 open-source consortium.
