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;
```
key = null;
      }
      
      entry = DummyEntry.create(key, hash, entry);
      ValueReference<Object, Object> valueRef = DummyValueReference.create(value);
      entry.setValueReference(valueRef);
    }
    segment.table.set(0, entry);
    segment.count = originalCount;
    int liveCount = originalCount / 3;
    assertEquals(1, segment.table.length());
    assertEquals(liveCount, countLiveEntries(map, 0));
    ImmutableMap<Object, Object> originalMap = ImmutableMap.copyOf(map);
    assertEquals(liveCount, originalMap.size());
    
    for (int i = 1; i <= originalCount * 2; i *= 2) {
      if (i > 1) {
        segment.expand();
      }
      assertEquals(i, segment.table.length());
      assertEquals(liveCount, countLiveEntries(map, 0));
      
      assertTrue(segment.count >= liveCount);
      assertTrue(segment.count <= originalCount);
      assertEquals(originalMap, ImmutableMap.copyOf(map));
    }
  }
  public void testRemoveIfWithConcurrentModification() {
    LocalCache<Integer, Integer> map =
        makeLocalCache(createCacheBuilder().concurrencyLevel(1).initialCapacity(1));
