Lock pattern

[Gary Gregory]

I wonder if anyone knows why Lock is not AutoCloseable.

This:

    public static boolean hasManager(final String name) {
        LOCK.lock();
        try {
            return MAP.containsKey(name);
        } finally {
            LOCK.unlock();
        }
    }


Seems lame in comparison to:

    public static boolean hasManager(final String name) {
        try (LOCK.lock()) {
            return MAP.containsKey(name);
        }
    }

Which, due to syntax really would be:

    public static boolean hasManager(final String name) {
        try (Object o = LOCK.lock()) {
            return MAP.containsKey(name);
        }
    }

Just wonderin'...
