The type hierarchy offers the method getFlags(IType) where it can be tested if 
a type is an interface or class. (Flags.isInterface). This API was added to 
allow us to get information about the type without creating an element info.

While debugging I saw that the implementation code in TypeHierarchy uses 
type.isInterface (throwing a JavaModelException):
public IType getSuperclass(IType type) {
	try {
		if (type.isInterface()) {
			return null;
		}
		return (IType) this.classToSuperclass.get(type);

	} catch (JavaModelException npe) {
		return null;
	}
}
Is this intended? Wouldn't it be possible to use the cached information to 
avoid the creation of the type info?
