> Project: Avro

> Components: java

> Attachments: specificDataClassLoader2.patch

>
> Right now SpecificData resolves classes for SpecificRecords by calling
> Class.forName(), which uses the ClassLoader used to load the SpecificData
> class. I believe this makes it impossible to deserialize into SpecificRecords
> that are loaded using a different ClassLoader.
> One relatively simple way to fix this limitations involves:
> * Adding a constructor to SpecificData that allows the user to specify a
> ClassLoader.
> * Changing the current protected constructor of SpecificDatumReader that
> takes a SpecificData to be public instead of protected.
> * Changing SpecificDatumReader to actually use the SpecificData that is
> passed into the constructor.
