### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version latest. ### Minimal reproduce step ConcurrentLongLongPairHashMap use optimistic locking to read data in Section, but if there is another thread that writing data to the same Section, and trigger the shrink process, then the index calculated using dirty capacity exceed the array size, an ArrayIndexOut0fBoundsException will be throw, which is not handled. Eventually the connection with client will be closed. ### What did you expect to see? ``` WARN org.apache.pulsar.broker.service.Servernx-[] Got exception, cause: java.lang.ArrayIndexOut0fBoundsException: Index 6821 out of bounds for length 4 096, stackTrace: java.lang.ArrayIndexOutOfBoundsException: Index 6821 out of bounds for length 4096 atorg.apache.pulsar.common.util.collections.ConcurrentLongLongPairHashMap$Section.get(ConcurrentLongLongPairHashMap.java:331) atorg.apache.pulsar.common.util.collections.ConcurrentLongLongPairHashMap.get(ConcurrentLongLongPairHashMap.java:204) at org.apache.pulsar.common.util.collections.ConcurrentLongLongPairHashMap.containsKey(ConcurrentLongLongPairHashMap.java:208) at org.apache.pulsar.broker.service.Consumer.getAckOwnerConsumer(Consumer.java:596) at org.apache.pulsar.broker.service.Consumer.individualAckNormal(Consumer.java:408) at org.apache.pulsar.broker.service.Consumer.messageAcked(Consumer.java:395) at org.apache.pulsar .broker .service.ServerCnx.handleAck(Server(nx.java:1456) at org.apache.pulsar.common.protocol.PulsarDecoder.channelRead(PulsarDecoder.java:145) ``` ### What did you see instead? , ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
