asmifier

asmifier is a web interface for ASM's ASMifier.

wut?

1. You give me Java code.
2. I compile the Java code to a class file.
3. I run the class file through ASMifier.
4. I give you the result.

asmifier's Issues

Missing method names

Minimal reproducible example:

public class MainClass{

}

Result:

import java.util.*;
import org.objectweb.asm.*;
public class MainClassDump implements Opcodes {
    
    public static byte[] dump () throws Exception {
        
        ClassWriter cw = new ClassWriter(0);
        FieldVisitor fv;
        MethodVisitor mv;
        AnnotationVisitor av0;
        
        cw.visit(52, ACC_PUBLIC + ACC_SUPER, "MainClass", null, "java/lang/Object", null);
        
        {
            mv = cw.visitMethod(ACC_PUBLIC, "", "()V", null, null);
            mv.visitCode();
            mv.visitVarInsn(ALOAD, 0);
            mv.visitMethodInsn(INVOKESPECIAL, "java/lang/Object", "", "()V", false);
            mv.visitInsn(RETURN);
            mv.visitMaxs(1, 1);
            mv.visitEnd();
        }
        cw.visitEnd();
        
        return cw.toByteArray();
    }
}

Problem is mv = cw.visitMethod(ACC_PUBLIC, "", "()V", null, null); and mv.visitMethodInsn(INVOKESPECIAL, "java/lang/Object", "", "()V", false);

Bug report: Missing <init> parameter when instantiate an object

Hi, there is an issue with your web application.
It works fine except when it has to deal with an object instantiation.

For example, assume we use this input:

import java.util.Date;

class ExampleClass
{  
    public static void main(String args[])
    {
        Date d = new Date();
    }
}

The output will include the line:

mv.visitMethodInsn(INVOKESPECIAL, "java/util/Date", "", "()V", false);

The parameter <init> is missing, I assume that string is interpreted by the browser as a HTML tag.
