See current javadoc for java.security.Provider, which has no /** */ code.

---begin---
    @Override
    public synchronized Object getOrDefault(Object key, Object defaultValue) {
        checkInitialized();
        return super.getOrDefault(key, defaultValue);
    }
---end---

which outputs:

---begin---
public Object getOrDefault(Object key,
                           Object defaultValue)

Description copied from interface: Map
Returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.

Specified by:
    getOrDefault in interface Map<Object,Object>
Overrides:
    getOrDefault in class Hashtable<Object,Object>
Parameters:
    key - the key whose associated value is to be returned
    defaultValue - the default mapping of the key
Returns:
    the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key
---end---

Note that @since/@throws are missing (there may be more) Users have no idea that this is a new method in Map unless they drill down.

If this was intentional, why?
