* Some public APIs have incorrect nullability annotations (both overly restrictive and overly permissive)

While there are competing ways to represent absence (`Optional`, "Null Object" pattern, method overloads),
it is unlikely that we'll be able to remove `null` entirely.

After migrating to Java 8, we can use pluggable type checkers to ensure that our annotations are consistent,

        documents[0] = new HashMap<>();
        documents[0].put(field, "これはテストです");

        documents[1] = new HashMap<>();
        documents[1].put(field, "検索エンジン");

    assertThat(Booleans.asList(ARRAY_FALSE).indexOf(true)).isEqualTo(-1);

        assertEquals(42, testBlock.wordCount); // Should be 34 + 8 = 42

        }

        @Override
        int readRDataWireFormat(byte[] src, int srcIndex) {
            // For testing purposes, we can return a fixed length or mock behavior
            // Create a dummy Name object for NbtAddress constructor
            Name dummyName = new Name(config, "DUMMY_NAME", 0, null);
            addrEntry[addrIndex] = new NbtAddress(dummyName, 0, false, NbtAddress.B_NODE);

        }
      }
    }
