congbobo184 opened a new pull request #14327:
URL: https://github.com/apache/pulsar/pull/14327
### Motivation
If individual ack batch message with transaction and abort this transaction,
we will redeliver this message. but this batch message some bit sit are acked
by another transaction and re consume this bit sit will produce
`TransactionConflictException`, we don't need to redeliver this bit sit witch
is acked by another transaction.
if batch have batch size 5
1. txn1 ack 0, 1 the ackSet is 00111
2. txn2 ack 2 3 4 the ack Set is 11000
3. abort txn2 redeliver this position is 00111
4. but now we don't filter txn1 ackSet so redeliver this position bitSet is
111111
### Modifications
When filter the message we should filter the bit sit witch is real ack or in
pendingAck state
