Asynchronous deserialization: String instead of real class type is attempted to be set as a field #149

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?

1. This class is used as a property in an abstract superclass: 
http://pastebin.com/L8DjuGhW
2. If deserialize the object synchronously, everything works fine. See the code 
in step 3. When it's not wrapped in a Runnable and started by an 
ExecutorService Thread it's deserialized correctly.
3. If I do it asynchronously (see: http://pastebin.com/mvWfV5Yy), I get this 
exception, because kryo tries to set an String instead of the MetaDataClass.

What is the expected output? What do you see instead?
Kryo serializes the field correctly, but when done asynchronously Kryo tries to 
set the field as a String.

What version of the Kryo are you using?
2.20

Please provide any additional information below.

The exact same code executed with kryo 2.22 yields this interesting error for 
every deserialized object (only the size values vary):
