> -----------------------------------------------------------------------
>
> Key: TWILL-125
> URL: https://issues.apache.org/jira/browse/TWILL-125
> Project: Apache Twill
> Issue Type: Bug
> Components: ext
> Affects Versions: 0.5.0-incubating
> Reporter: Rob Morgan
> Assignee: Rob Morgan
>
> BundledJarRunner attempts to load the main class using Class#newInstance. The call to newInstance will then attempt to find and invoke the class's zero-args constructor. This will throw an InstantiationException if there is no zero-args constructor to be found.
> Loading the main class is unnecessary. Since main is always static it can be invoked with a null target object.
