Hello,
first of all I'd like to thank you for creating and maintaining XStream. It
helps us a great deal in most of our unit tests.
We're using XStream 1.4.4 and as we switched from Sun14ReflectionProvider to
its superclass PureJavaReflectionProvider I noticed breaking tests. After some
debugging I found out that objects read from XML have properties set, which are
not part of the XML documents. I took a closer look at those properties and
realized that they're being initialized on object creation. Nothing special so
far. So I debugged again with Sun14ReflectionProvider and realized that those
properties, which should be initialized on object creation, remain null.
Long story short I think the Sun14ReflectionProvider is broken. It does not
behave the same as its superclass although it should, but only in a more
efficient way. It does not invoke the public default constructor as expected.
I've provided a unit test and resources to reproduce this behaviour.
Best regards
