[jira] [Commented] (BCEL-312) AssertionViolation: INTERNAL ERROR Please adapt StringRepresentation to deal with ConstantPackage in Verifier Pass 2

    [ https://issues.apache.org/jira/browse/BCEL-312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16879694#comment-16879694 ] 

Gary Gregory commented on BCEL-312:
-----------------------------------

The {{Hello}} class file you provided is not in a Java package, therefore I cannot add it along with all of your other classes with the exact same unpackaged class name :( to our {{src/test/resources}} folder.

It would be great if you could provide class files in a package named after _something_ like jqf_0, jqf_1, and son on. This would allow us to add these files as {{src/test/resources/jqf_0/Hello.class}}, {{src/test/resources/jqf_1/Hello.class}}, and so on.

> Verifier pass 2 throws an INTERNAL ERROR on malformed input instead of reporting verification failure.
> h1. Steps to reproduce:
>  
> Save the attached file as "Hello.class" and run:
> java -cp <classpath> org.apache.bcel.verifier.Verifier Hello
>  
> The file Hello.class was generated automatically by the fuzzer JQF ([https://github.com/rohanpadhye/jqf]).
> h2. Expected output:
> VERIFIED_REJECTED
> h2. Observed output:
> JustIce by Enver Haase, (C) 2001-2002.
> <http://bcel.sourceforge.net>
> <http://commons.apache.org/bcel>
>  
> Now verifying: Hello
>  
> Pass 1:
> VERIFIED_OK
> Passed verification.
