Immutable object is not serialized with yaml.dump

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create Immutable class with constructor, only getters
2. serialize with yaml.dump(), no attributes are serialized
3. add a setter to any attribute
4. serialize again, this attribute gets serialized

What is the expected output? What do you see instead?
Serialized immutable with all attributes, only raw class, no attributes

What version of SnakeYAML are you using? On what Java version?
SnakeYAML 1.11-SNAPSHOTS, Java 1.6

Please provide any additional information below. (Often a failing test is
the best way to describe the problem.)
see attached Test

Have you tried DumpOptions ?

<code language="java">
DumpOptions o = new DumpOptions();
o.setAllowReadOnlyProperties(true);
Yaml yaml = new Yaml(o);

Sorry, didn't try yet. I was just curious why a missing setter affects the 
serializing. I thought that getters must be enough.

By default, SnakeYAML can only process classes that conform to the JavaBean 
specification. A class without a setter is no JavaBean and it requires manual 
definition.
