> camel-dozer: Multiple contexts / bundles - Does not use the correct
> classloader
> -------------------------------------------------------------------------------
>
> Key: CAMEL-8689
> URL: https://issues.apache.org/jira/browse/CAMEL-8689
> Project: Camel
> Issue Type: Bug
> Components: camel-dozer
> Affects Versions: 2.15.1
> Reporter: Raúl Kripalani
> Assignee: Raúl Kripalani
> Fix For: 2.14.3, 2.16.0, 2.15.3
>
>
> Dozer is a tough library to work with in a multi-module context, because of
> its use of singletons for configuration. In an OSGi environment, each bundle
> will have its own classloader but Dozer's architecture makes it impossible to
> cater for this scenario nicely. Unfortunately, it expects a single
> container-wide classloader configured in the BeanContainer singleton.
> In Camel we worked around this by providing a custom DozerClassLoader
> implementation that is aware of the Camel Context, but what happens if we are
> sharing Dozer across multiple Camel Contexts? The most recently initialized
> context will override the container-wide classloader.
> We need a solution such that the classloader can dynamically change based on
> the Camel Context that is using the component.
