ClassCastException in Representer

[GoogleCodeExporter]

Hi,

In my project I serialize lists of Class Objects (List<Class<Object>> for 
example). I wrote a Representer for Class Objects. If I try to dump such 
a list I get a ClassCastException within the Representer.

Exception in thread "main" java.lang.ClassCastException: 
sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be 
cast to java.lang.Class
    at 
org.yaml.snakeyaml.representer.Representer.checkGlobalTag(Representer.java
:184)

You can avoid this exception with the following code (Representer 184):

Class<? extends Object> t;
if (arguments[0] instanceof ParameterizedType) {
    t = (Class<? extends Object>) ((ParameterizedType) 
arguments[0]).getRawType();
} else {
    t = (Class<? extends Object>) arguments[0];
}

The same exception occurs in the Constructor on line 280.

I hope this will help to improve this nice tool.

Kind regards
Maxim

Can you please provide a test to reproduce the problem ? What is the version ? 
Have you 
tried the latest source ?

It seems to be related to issue 61. But I am afraid your business case covers 
more then 
it is done for issue 61.

Hey py4fun,

as you wished I wrote a small test which reproduces the exception. I tested the 
unit
test with version 1.6. But the same happens in the current source, too.

Kind regards
Maxim
