ProGuard Java Optimizer and Obfuscator / Bugs / #607 java.lang.VerifyError: Bad type on operand stack

Eric Lafortune - 2016-06-11

Thanks for your report. I can't seem to reproduce the problem yet. Which compiler are you using? Do you have a small sample class that I can build and run?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

  Eric,
  Thank you for getting back to me. I'm compiling and running with Java 1.8. The constructor takes an MSExcel file as an input stream and the remaining arguments can be "," and false. Attached is a file in case you don't have MSExcel. The exception happens in the construction of this class.
  
  Thanks,
  Vico

  This code is falling at runtime. I believe it's the multi-exception syntax in the catch is the issue. If I changed it to catch(Exception e) it works. Here is my proguard config,source code and exception

I've also run into a "VerifyError: Bad type on operand stack" problem. I am not using multi-catch. I am compiling with JDK 1.7.0_45 and tried both Proguard 5.2.1 and 5.3.1. I will email you a JAR and Proguard settings that consistently reproduce the problem, hopefully that helps!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

I'm also running into this issue. The simplest case to reproduce is below. The catch block catches multiple exceptions and gives "Exception in thread "main" java.lang.VerifyError: Bad type on operand stack".

As previously mentioned, changing the catch to just catch Exception, or having separate catch blocks for each exception both work. I'm compiling with jdk 1.8.0_91 and using proguard 5.3.2

package com.doug.test;

import java.security.NoSuchAlgorithmException;
import java.util.Random;
import javax.crypto.NoSuchPaddingException;


public class App {
  public static void main(String[] args) {

    System.out.println("App:main() Test16: Test multi-exception...");
    Random rand = new Random();
    int n = rand.nextInt(1);
    try {

      if (n > 0) {
        throw new NoSuchAlgorithmException();
      } else {
        throw new NoSuchPaddingException();
      }
    }

    catch ( NoSuchPaddingException | NoSuchAlgorithmException e){
      System.out.println(e.getMessage());
    }
  }
}

Himanshu Patel - 2017-04-14

Hi Eric,

Has this bug been fixed in v5.3.2? I am getting this "java.lang.VerifyError: Bad type on operand stack" error at run time. I feel i too have a similiar problem in my code.

I am getting the similiar error. Below is the error stack. I have a source java class that has multi exception syntax in it. I am using ProGuard v5.3.2, Maven Proguard Plugin with plugin version 2.0.14.

My proguard configuration is after the error stack trace.

Error Stack:

I am also receiving this error when running progaurd6.0.3 on any code using multi-catch.
Simply changing my multi-catch blocks to single catch blocks, and duplicating the code resolves the issue, but it is a serious hinderance.
Why has this not been fixed? And still on "works for me" status.

  Do you have a reproduction? I was trying to reproduce this one to narrow it down, but I used one of the other examples above, and couldn't get it to happen.

    Reviewing the issue again, I can reproduce it with the sample of Doug Duthie (higher up). Sorry about the delay. I'll look into it.

      The problem in Doug's sample is masked by -ignorewarnings. Specifying -libraryjarswith the Java 9 runtime jmods/java.base.jmod instead of the Java 8 runtime lib/rt.jar solves the issue. ProGuard can then find the referenced javax.crypto.NoSuchPaddingException and its class hierarchy.

        Hey Eric, what you pointed out was helpful. It seems Doug was referencing the java rt.jar as though it were located on MacOS (I use Mac), rather than Windows, and given the rest of his library references, I'm certain he's using windows, so his rt.jar reference was likely pointing to something nonexistent.
        Doug try C:\Program Files\Java..etc ensure your library reference is correct.
        
        I also realized I was improperly referencing rt.jar; I fixed my reference to 1.8's rt.jar and all of my problems were gone.
        However, I couldn't find any documentation on migrating from 1.8 to 1.9 and above. I've tried referencing java.base.jmod as you've suggested:
        
        Reading library directory [/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/jmods/java.base.jmod]
        
        However, doing this results in the exact same problem as previously existed, ProGaurd couldn't find any of the java class references from this.
        Any ideas why this would be working for you and not me?
        
        EDIT: Just found a bug report regarding this, it's still open but as priority 7: https://sourceforge.net/p/proguard/bugs/551/

        PgoGuard 6.0 is out, so issue #551 should have been closed. If you still see a similar problem, make sure that you specify the runtime libraries and other external libraries that your application requires:
        
        Choose a suddiciently high version of Java.
        
        You may need to specify other relevant jmod libraries beside java.base.jmod. ProGuard doesn't automatically load additional jmod files based on any metadata that might be present.
        
        The console output lists any classes that are missing and that may lead to corrupt output. Avoid -ignorewarnings or -dontwarn unless you know why it's applicable.
        
        You can currently find some documentation in the examples, e.g. examples/standalone/applications.pro

        Using "(!.jar;!module-info.class)" at the end of the jmod path as suggested in the examples resulted in the library not being able to be read. Not sure why the example uses that. However, I did get it to work without the "(!.jar;!module-info.class)".
        Thanks for all of your help Eric.
        
        I believe you can close this request. Since the OP didn't specify any libraryjar at all, and Dough and I both incorrectly referrenced our java librarys, I believe it's safe to conclude that the output jars being broken upon usage of a multi exception catch line as reported in this bug is only a direct result of not properly specifying our java runtime libs.
