Check whether the given class is cache-safe in the given context,
i.e. whether it is loaded by the given ClassLoader or a parent of it.

@param clazz       the class to analyze
@param classLoader the ClassLoader to potentially cache metadata in
Check whether the given class is cache - safe in the given context i . e . whether it is loaded by the given ClassLoader or a parent of it .
