Brian GoetzJava Language Architect at Oracle recently updated JEP Design 828039, Classfile APIto provide background on how this concept will evolve and eventually replace the Java bytecode manipulation and analysis framework, ASM, which Goetz describes as “an old codebase with a lot of legacy baggage.” This JEP proposes to provide an API for parsing, generating and transforming Java class files. This JEP will initially serve as an internal replacement for ASM in the JDK with plans to open it as a public API.
