BodyStripper

ASM visitor that replaces every CONCRETE method's code with a 2-byte aconst_null; athrow stub, keeping the method's signature, exceptions and declaration annotations (code/type annotations go with the body). Wired as tiny-remapper's extraPreApplyVisitor so the whole pipeline (remap + write) processes stubs, not full bodies — the compiler reads signatures/constants/annotations, never bodies, for a classpath class. The resulting symbol jar is compile-only (never loaded/verified/run), so an under-sized maxLocals or a throwing constructor is harmless. Abstract/native methods (no Code attribute) pass through untouched.
