Issue with BeanUtil.deserialize()

[Murali Krishnan <cm...@yahoo.com>]

Hello,
BeanUtil.deserialize() throws a java.lang.InstantiationException when trying to deserialize an xml fragment. The java classes were generated using wsdl2java and jaxbri binding. One of the xml elements is 'notificationInterval' with data type 'xs:duration' which gets mapped to javax.xml.datatype.Duration by JAXB.

When an xml fragment containing this type is being unmarshalled, BeanUtil fails because it is trying to instantiate an abstract class (since Duration is abstract). 
Is there a way to get past this problem?

Attached are the generated classes and the xml fragment.

Thanks,
Murali

Note: I was able to get past a similar problem with XMLGregorianCalendar by using jaxb customization (to create java.util.Calendar)
