Folks, Found we still use @Nullable annotation.
What's the reason for using it? Everything is Object and Nullable :) How about get rid of @Nullable usages and restrict its usage by checkstyle plugin? BTW, We already "do not use @NotNull annotation" (с) Coding Guidelines [1] which may have some cense in contrast to @Nullable. But I see a lot of usages at code. How about to get rid of @NotNull too and to add such check to checkstyle plugin too? [1] https://cwiki.apache.org/confluence/display/IGNITE/Coding+Guidelines#CodingGuidelines-@Annotations
