I've tried to profile the benchmark and:
1. results are very unstable :( I don't know why, maybe because of GC?
because...
2. `GC overhead limit exceeded`
```
Iteration 14: 126017.810 ops/ms
Iteration 15: 91305.667 ops/ms
Iteration 16: 43366.582 ops/ms
Iteration 17: <failure>
java.lang.OutOfMemoryError: GC overhead limit exceeded
at java.util.Arrays.copyOf(Arrays.java:3236)
at
java.io.ByteArrayOutputStream.toByteArray(ByteArrayOutputStream.java:191)
```
It looks like there is some resource leak
