The difference is that the exception now contains enough information to start
you discovering what is wrong
> Configuration to include name of failing file/resource when wrapping an XML
> parser exception

> Key: HADOOP-9447
> URL: https://issues.apache.org/jira/browse/HADOOP-9447
> Project: Hadoop Common
> Issue Type: Improvement
> Components: conf
> Affects Versions: 3.0.0
> Reporter: Steve Loughran
> Priority: Trivial
>
> Currently, when there is an error parsing an XML file, the name of the file
> at fault is logged, but not included in the (wrapped) XML exception. If that
> same file/resource name were included in the text of the wrapped exception,
> people would be able to find out which file was causing problems
