Andrey Gura commented on IGNITE-2080:
-------------------------------------
1) All methods of {{GridUnsafe}} use bigendian byte order. Client code is
reposonsible for correct endianness handling.
2) Of course, we can always uses aligned aware methods. But why we need do it
in cases where we sure that pointer/offset already aligned?
3) I can be wrong but volatile access always requires aligned access.

> In order ot reproduce it need to do following:
> # Copy [^benchmark-offheap.properties] file into {{modules/yardstick/config}}
> directory.
> # Build yardstick {{mvn -B clean package -Prelease,benchmarks -DskipTests -pl
> modules/yardstick -am}}
> # Run benchmark {{./bin/benchmark-drivers-start.sh
> config/benchmark-offheap.properties}} (do it from {{yardstick}} module
> directory)
> The problem isn't related with JIT (reproduces with -Xint option).
> Also see attached logs and [core
