With Xstream 1.4.14 Error : Cannot deserialize object with new readObject()/writeObject() for class XMLGregorianCalendarImpl

[Rahul Bhagat]

Hello,

I'm getting the following error while migrating from JDK 1.8 to JDK 11. 

Can someone please help/ advise?

Thanks,

Rahul.

Unfortunately the internals of the class have been changed in the Java runtime
entirely. Since these classes are meant to be JDK internal, this is something
that can happen with each new Java version.

You may implement a custom converter for a XMLGregorianCalendar using the
javax,xml.datatype.DataFactory to create the instance (similar to XStream's
DurationConverter, that belongs into the same area).

However, your unmarshal method might have to handle also the existing XML
structure for this type. See e.g. XStream's AtomicIntegerConverter how this
can be achieved.

Cheers,
