I was unable to find any issue or discussion related to what I described below and so decided to create a ticket.

After change 73e382fa877f80994817a136b0adcc4365ccd904 `LocalCache` implements its own versions of methods like `computeIfAbsent` and `computeIfPresent`. These replace previous implementations inherited from `ConcurrentMap` with ones that delegate to unconditional call to `compute` with customised lambda e.g. `computeIfAbsent`:

```java
 return ((v = get(key)) == null &&
                (newValue = mappingFunction.apply(key)) != null &&
                (v = putIfAbsent(key, newValue)) == null) ? newValue : v;
```
becomes:

```java
compute(key, (k, oldValue) -> (oldValue == null) ? function.apply(key) : oldValue);
```

This has side effect that even if value is already present it is replaced by itself which confuses removal listener that will report value being removed with `RemovalCause.REPLACED`. Stats are possibly also incorrect (not used them to date so I am not sure).

Below test case reproduces this behaviour.

```java
List<RemovalNotification> notifications = new ArrayList<>();

Cache<Integer, Integer> cache = CacheBuilder.<Integer, Integer>newBuilder()
        .removalListener((RemovalListener<Integer, Integer>) notifications::add)
        .recordStats()
        .build();

cache.asMap().computeIfAbsent(1, integer -> integer + 1);
cache.asMap().computeIfAbsent(1, integer -> integer + 1);

assert notifications.size() == 1;
assert notifications.get(0).getCause() == RemovalCause.REPLACED;
assert cache.stats().evictionCount() == 0;
assert cache.stats().loadCount() == 2;
```
Object four = new Object();
    Object five = new Object();
    map.put(one, two);
    ticker.advance(1);
    map.put(two, three);
    ticker.advance(1);
    map.put(three, four);
    assertTrue(listener.isEmpty());
    ticker.advance(1);
    map.put(four, five);
    assertNotified(listener, one, two, RemovalCause.EXPIRED);
    assertTrue(listener.isEmpty());
  }
  public void testRemovalListener_size() {
    QueuingRemovalListener<Object, Object> listener = queuingRemovalListener();
    LocalCache<Object, Object> map =
        makeLocalCache(
            createCacheBuilder().concurrencyLevel(1).maximumSize(2).removalListener(listener));
    assertTrue(listener.isEmpty());
    Object one = new Object();
    Object two = new Object();
    Object three = new Object();
    Object four = new Object();
    map.put(one, two);
    map.put(two, three);
    assertTrue(listener.isEmpty());
    map.put(three, four);
    assertNotified(listener, one, two, RemovalCause.SIZE);
    assertTrue(listener.isEmpty());
  }
