Description
I have a class which encapsulates a BufferedImage and I have overriden

> IOException,
> ClassNotFoundException

> The xml produce by calling writeObject is well formed, it can be found

> The issue that I have is the the stream that is passed into readObject

Hi Jon,
I close this now as "cannot reproduce". I've added an acceptance test where a buffered images are serialized into XML and back and this works fine. However, I fixed recently a bug in XSTR-508 that might have affected and solved your use case also. You may give the head revision a try.

Jörg Hi Jon,
one last comment. Meanwhile I had to detect that the added acceptance test will corrupt the memory of the JVM, since a BufferedImage contains (at least in the Linux JVM of Sun) internal classes that have a member variable that represents a pointer to native memory. At deserialization time XStream will overwrite this member also and the memory management of the JVM gets corrupted. So, unless somebody will write custom converters for a BufferedImage and all its contained data, it is not possible to marshal a BufferedImage in a safe way.
