I've been trying to work with classfile api, and:
- `AttributesProcessingOption` is unused, does nothing?
- Classfiles with oak format seem to be unparsable. They also cannot be written. (maxStack/maxLocals in Code attribute depend on classfile version). Constants such as `JAVA_1_VERSION` exist in `java.lang.classfile.ClassFile`.
