Boolean handling is very broken

Boolean handling is broken due to a bug in
QTagImplPlugin.vm

What it does is:

#if($method.returns.value != "boolean")
return result;
#else
return Boolean.getBoolean(result);
#endBoolean.getBoolean(result)

According to the JavaDocs:
static getBoolean(String name)
Returns true if and only if the **system property** named by the argument exists and is equal to the string "true".

You want something like this rather:

return Boolean.valueOf(result).booleanValue()

(You also need to change the "test" case as the output will change)
