Alexandr Kuramshin commented on IGNITE-6200:
--------------------------------------------
When writing a serializable object by the {{OptimizedObjectOutputStream}} the
following logic occurs:
1. Initial call to {{OptimizedObjectOutputStream.writeObject0}} will find
{{OptimizedClassDescriptor}} and it's {{write}} consequently invokes
{{OptimizedObjectOutputStream.writeSerializable}}
2. The {{writeSerializable}} initialize {{curObj}} to the serializable object
instance and invokes its {{writeObject}} method.
3. If the implementations will call
{{OptimizedObjectOutputStream.defaultWriteObject}} right away then no error
occurs.
4. But if the implementation first call
{{OptimizedObjectOutputStream.writeObject}} then {{curObj}} will be reset and
consequent call causes the error.
{{org.dom4j.QName}} has the such implementation of {{writeObject}} method.
The fix is simple: store {{curObj}} reference at the start of
{{OptimizedObjectOutputStream.writeObject0}}, and restore at the end.
> org.dom4j.QName can't be serialized
