> Preserve ConversionException cause
> ----------------------------------
>
> Key: CONFIGURATION-692
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-692
> Project: Commons Configuration
> Issue Type: Improvement
> Components: Type conversion
> Affects Versions: 2.2
> Reporter: Lars W
> Priority: Minor
> Fix For: 2.3
>
>
> When improving the error message of the ConversionException thrown by the
> ConversionHandler in AbstractConfiguration.java:1768 the cause is lost.
> If for example a string is converted into a URL the MalformedURLException,
> that contains the actual reason for the failed conversion, is gone.
> A possible fix for that could be to attach the cause to the new
> ConversionException:
> AbstractConfiguration.java:1768:
> throw new ConversionException(
> String.format(
> "Key '%s' cannot be converted to class %s. Value is: '%s'.",
> key, cls.getName(), String.valueOf(value)), cex.getCause());
>
