unable ro write/readClass

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I first write a type for objects, that will be following later on
Output out = new Output(myOutStream);
Kryo k = new Kryo();
k.writeClass(out, String.class);
out.flush();

2. it just puts 0x03 on the wire

3. doing a k.readClass(in) just results in:
com.esotericsoftware.kryo.KryoException: Buffer underflow.
    at com.esotericsoftware.kryo.io.Input.require(Input.java:157)
    at com.esotericsoftware.kryo.io.Input.readInt(Input.java:302)
    at com.esotericsoftware.kryo.Kryo.readClass(Kryo.java:594)

What is the expected output? What do you see instead?
Documentation states, that the complete class name is to be transferred over 
the wire.
And readClass() should give me String.class instead of throwing an exception, 
of course.

What version of the Kryo are you using?
2.16

Please provide any additional information below.
I do not use class registration or custom serializers

Works for me.

Kryo kryo = new Kryo();
Output output = new Output(1024);
kryo.writeClass(output, String.class);
System.out.println(kryo.readClass(new Input(output.toBytes())));

• Changed state: Invalid

so it's okay that serializing String.class doesn't actually send 
"java.lang.String" over the wire?

Primitive, primitive wrappers, and String are regsitered by default.
