------------------------------------
Summary: 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
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());
