> Project: Commons BCEL
> Issue Type: Bug
> Components: Verifier
> Affects Versions: 6.2
> Reporter: Rohan Padhye
> Priority: Major
> Attachments: Hello.class

> h1. Steps to reproduce:
>
> Save the attached file as "Hello.class" and run:
> java -cp <classpath> org.apache.bcel.verifier.Verifier Hello

> h2. Expected output:
> VERIFIED_REJECTED
> h2. Observed output:
