Actually you don't need to use ASM. You can just create two jars, one
contains `org/apache/twill/internal/utils/Class1.class`, the other has
`org/apache/twill/internal/utils/Class2.class`. Then create a `URLClassLoader`
from that two jars, with `null` as the parent. Then load `Class1` and `Class2`
from that classloader and provide the both classes to the
`ApplicationBundler.createBundle` method.

> Key: TWILL-182
> URL: https://issues.apache.org/jira/browse/TWILL-182
> Project: Apache Twill
> Issue Type: Bug
> Components: core
> Affects Versions: 0.7.0-incubating
> Reporter: Martin Serrano
> Fix For: 0.8.0
>
>
> If two jars obtained from *different* classpath locations have the same name
> but different contents, one will overwrite the other. The dependency code
> correctly finds the jars (uses the full path in the HashSet which accumulates
> the deps) but when the bundle is created the jars are written to {{/lib}}
> under their name. This results in one overwriting the other.
> While this is not a likely occurrence, it occurs for us in our development
> environment because our published jar names are built up from their project
> hierarchy. For example the model project for our sdk is in {{.../sdk/model}}
> and will be on the classpath as {{.../sdk/model.jar}} and published as
> {{sdk-model.jar}}.
> In practice however this could occur with any jar name and would be more
> likely over time.
> The {{ApplicationBundler}} could detect this and re-write the name with some
> part of the path or suffix to ensure the name is unique.
