Hi Guys,

I am using com.thoughtworks.xstream v1.3.1.  And trying to load XML file to 
java object.

While doing so getting CannotResolveClassException error for the class 
CategoryRuleMap which is present at the required location.

This functionality was working with Sonar plugin api - 1.10. I have upgraded 
Sonar plugin api to 3.0 and this has stopped working. Any clue what could be 
the issue.

Below is the code snippet I have:

        InputStream input = getClass().getResourceAsStream(CATEGORY_MAP_FILE);
    categoryRuleMap = new CategoryRuleMap();

    XStream xstream = new XStream();
    xstream.alias("CategoryRuleMap", CategoryRuleMap.class);
    xstream.alias("category", CategoryMap.class);
    xstream.aliasAttribute(CategoryMap.class, "name", "name");
    xstream.alias("rule", String.class);
    xstream.addImplicitCollection(CategoryRuleMap.class, "categories");

    xstream.fromXML(input, categoryRuleMap);

Error trace:
