Hello,
I am using Hessian version 3.1.2 and I have an exception when I try to
deserialize my object:
java.lang.UnsupportedOperationException:

JavaDeserializer.java:228)
This is the code that I am using to deserialize my object is:
ByteArrayInputStream bais = new ByteArrayInputStream(data);
Hessian2Input in = new Hessian2Input(bais);
Object o = in.readObject();
in.close();
After some debugging, I have found that the problem is in this part of the
method "Hessian2Input.readObject()":
case 'v': {
int ref = readInt();
String type = (String) _types.get(ref);
int length = readInt();
Deserializer reader;
reader = findSerializerFactory().getObjectDeserializer(type);
return reader.readLengthList(this, length);
}
The type is a custom class which implements java.util.List and the reader
is an instance of CollectionDeserializer wich extends the class
AbstractDeserializer.
The problem is that CollectionDeserializer doesnt't override the
readLengthList method of the class AbstractDeserializer which throws an
UnsuportedException.
Is it a bug, or did I miss something?
