Hi Tesla, In short, you can't. To write a local variable, the only way provided by the ClassFile API is to create a java.lang.classfile.instruction.LocalVariable, and send it to CodeBuilder::with, or just calling CodeBuilder::localVariable. The LocalVariableInfo interface exists to faithfully represent the contents of a LocalVariableTable attribute for class file parsing.

I'm using classfile. It seems that the interface is sealed and either implementations are not exported. Best, Tesla
