Comments
EVALUATION Test consists of the serialized binary file and a source of the class Test1.java, which was serialized. Problematic code is here: ObjectInputStream in_stream = new ObjectInputStream(new FileInputStream(FilePath)); ann_ref_local = (Test1)in_stream.readObject(); till 6u26-rev-b23 (inclusive) this code restores Test1 instance from the serialized file. 6u26-rev-b24 causes exception. In other words, deserialization is unable to restore a previously serialized class. This is a clear compatibility issue.
