Karl Pauls commented on FELIX-674:
----------------------------------
Yes, I know that the original exception is lost. I have a fix that lets the
exception bubble up and I don't see any issues committing it. Still, I was
wondering about your exact use-case because as described above, the use-case
you mention should be covered because it would trigger a NoClassDefFoundError
which will make it to the caller. Are you just interested in the general
diagnostic messages we embed in our ClassNotFoundExceptions? In this case I can
understand why you are interested in the original exception...

> Key: FELIX-674
> URL: https://issues.apache.org/jira/browse/FELIX-674
> Project: Felix
> Issue Type: Improvement
> Components: Framework
> Affects Versions: felix-1.0.4
> Reporter: Don Brown
> Assignee: Karl Pauls
> Fix For: felix-1.2.0
>
>
> We (Atlassian) are in the middle of a rollout of our new plugin
> framework that has Felix at its core. The plugin system operates on
> top of existing Java webapps as an embedded container, with plugins
> exposing XML configuration defining what plugin extension points they
> implement. When the plugin is started, the web application needs to
> resolve that class name to a class instance, which is currently
> implemented using Bundle.loadClass().
> However, the Bundle.loadClass() method is swallowing the root cause of
> any exception causing the class to not be resolved, so if it is trying
> to load FooPlugin, which fails due to a missing class dependency of
> FooPlugin, Bundle.loadClass() throws a ClassNotFoundException that
> says FooPlugin wasn't found, which is misleading. I traced it down
> (version 1.0.4) to ModuleImpl.getClass(), which swallows any
> exceptions by only logging them as a warning. Unfortunately, the warn
> messages are given a lower priority by the host application due to a
> number of warnings that happen as a natural part of the loading
> sequence.
> This ticket asks for better error reporting ideally through proper chained
> exceptions.
