Byte Buddy is a code generation and manipulation library for creating and modifying Java classes during the runtime of a
Java application and without the help of a compiler. Other than the code generation utilities
that [ship with the Java Class Library](https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/Proxy.html), Byte
Buddy allows the creation of arbitrary classes and is not limited to implementing interfaces for the creation of runtime
proxies. Furthermore, Byte Buddy offers a convenient API for changing classes either manually, using a Java agent or
during a build.

Java version compatibility
==========================

The following table lists the minimal versions of Byte Buddy that is required need to support a certain Java 
class file version without experimental support. The oldest supported Java version is Java 5, whereas class files
of any older version can be transformed. As of 1.17.0, support will extend to new Java versions unless previously
unknown class file features are discovered. This is possible through Byte Buddy's support of the Class File API. 

| Byte Buddy version | Supported Java version | Minimum JVM version |
