Statement: Statement [queries=[DELETE FROM integers i1 WHERE i>(SELECT MAX(i) FROM integers WHERE i1.i<>i)], expected=OK]       Caused by: org.apache.ignite.lang.IgniteException: IGN-CMN-65535 TraceId:d3ee7af7-6d38-4ca4-bad5-86113048e6e9 IGN-CMN-65535 TraceId:d3ee7af7-6d38-4ca4-bad5-86113048e6e9 Index 50 out of bounds for length 49       Caused by: org.apache.ignite.lang.IgniteException: IGN-CMN-65535 TraceId:d3ee7af7-6d38-4ca4-bad5-86113048e6e9 Index 50 out of bounds for length 49       Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 50 out of bounds for length 49

 

The reason for given issue is non-threadsafe org.apache.ignite.internal.tx.impl.TransactionImpl#enlistedResults

So that

private volatile List<CompletableFuture<?>> enlistedResults = new ArrayList<>();

was updated with

private final List<CompletableFuture<?>> enlistedResults = new CopyOnWriteArrayList<>();
