> Project: Ignite
> Issue Type: Task
> Reporter: Viacheslav Blinov
> Priority: Major

> Issue detected by SpotBugs. Specifically the warning reported is:
> {noformat}
> H M VO_VOLATILE_INCREMENT VO: Increment of volatile field
> org.apache.ignite.internal.tx.impl.TxManagerImpl$TxContext.inflights in
> org.apache.ignite.internal.tx.impl.TxManagerImpl.lambda$addInflight$21(boolean[],
> UUID, TxManagerImpl$TxContext) At TxManagerImpl.java:[line 843]
> H M VO_VOLATILE_INCREMENT VO: Increment of volatile field
> org.apache.ignite.internal.tx.impl.TxManagerImpl$TxContext.inflights in
> org.apache.ignite.internal.tx.impl.TxManagerImpl.lambda$removeInflight$22(UUID,
> TxManagerImpl$TxContext) At TxManagerImpl.java:[line 858]
> {noformat}
> Increments/Decrements of volatile fields aren't atomic. If more than one
> thread is incrementing/decrementing the field at the same time,
> increments/decrements could be lost.
> 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
