             Summary: BeanHelper exception on XMLConfiguration builder.getConfiguration()
                 Key: CONFIGURATION-627
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-627

            Priority: Minor


Creating an *XMLConfiguration* from a file with a builder:
{code:java}
builder =
        new FileBasedConfigurationBuilder<XMLConfiguration>(
                XMLConfiguration.class)
                        .configure(params.xml()
                                .setFileName(
                                        propsFile.getCanonicalPath())
                                .setValidating(false));

config = builder.getConfiguration();
{code}

Causes a non-halting exception originating in *org.apache.commons.configuration2.beanutils.BeanHelper*,
method 
*private static boolean isPropertyWriteable(Object bean, String propName)* with parameters
*XMLConfiguration*, *"validating"*.
