> Issue detected by SpotBugs. Specifically the warning reported is:
> {noformat}
> M M JLM_JSR166_UTILCONCURRENT_MONITORENTER JLM: Synchronization performed on java.util.concurrent.atomic.AtomicReferenceArray in org.apache.ignite.internal.network.LazyStripedExecutor.executorFor(short)  At LazyStripedExecutor.java:[line 88] {noformat}
> Instances of java.util.concurrent.atomic classes have their own concurrency control mechanisms that are orthogonal to the synchronization provided by the Java keyword {{{}synchronized{}}}. For example, synchronizing on an {{AtomicBoolean}} will not prevent other threads from modifying the {{{}AtomicBoolean{}}}.
> Such code may be correct, but should be carefully reviewed and documented, and may confuse people who have to maintain the code at a later date.
> Investigate whenever this is a false-positive and we should suppress it, or we should make a proper fix.
> At the result of investigation corresponding TODO should be removed in spotbugs-excludes.xml
