Title: treating not null and null with new resources of Java 8

Treating null and not null using java.util.Objects will faster than using operator, because the JIT action.
Running the bench with JMH the result was:

Benchmark (size) Mode Samples Mean Mean error Units
m.NullBenchmark.isNotNull 1000000 thrpt 20 251.020 36.826 ops/s
m.NullBenchmark.isNotNullUtils 1000000 thrpt 20 286.275 2.388 ops/s
m.NullBenchmark.isNull 1000000 thrpt 20 289.536 2.463 ops/s
m.NullBenchmark.isNullUtils 1000000 thrpt 20 290.583 2.101 ops/s

Another points of null can replace with Optional or using new methods on map.
