Review Comment:
Another thing I realised is that the page size is adjusted further down this
method for the JDBC use case. So validating the value at the start of this
method, before that later change occurs, is likely to give the wrong behaviour.

> pageSizeBytes/pageLimitBytes combination can cause Address full

> Key: ARTEMIS-4973
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4973
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 2.36.0
> Reporter: Howard Gao
> Assignee: Howard Gao
> Priority: Major
> Time Spent: 2h
> Remaining Estimate: 0h
>
> There is an edge case where adjusting pageSizeBytes can cause "Address is
> full" errors, even though the address is not full.
> Do we need to enforce that pageSizeBytes <= pageLimitBytes?
> Reproducer steps:
> Step 1: configure pageSizeBytes == pageLimitBytes == 1mb:
> $ cat my.broker.properties
> addressSettings."FOO".pageSizeBytes=1048576
> addressSettings."FOO".pageLimitBytes=1048576
> addressSettings."FOO".maxSizeBytes=1048576
> addressSettings."FOO".pageFullMessagePolicy=FAIL
> addressConfigurations."FOO".routingTypes=MULTICAST
> addressConfigurations."FOO".queueConfigs."FOO".name=FOO
> addressConfigurations."FOO".queueConfigs."FOO".address=FOO
> addressConfigurations."FOO".queueConfigs."FOO".routingType=MULTICAST
> Step 2: run broker
> bin/artemis run --properties my.broker.properties
> Step 3: produce 15 messages
> $ bin/artemis producer --user admin --password admin --destination
> topic://FOO --message-count 15 --message-size 100000 --protocol amqp
> Step 4: observe paging started on the destination (but the page size is
> 328kb, can hold more messages)
> INFO [org.apache.activemq.artemis.core.server] AMQ222038: Starting paging on
> address 'FOO'; size=1107003 bytes (11 messages); maxSize=1048576 bytes (-1
> messages); globalSize=1107003 bytes (11 messages); globalMaxSize=1073741824
> bytes (-1 messages);
> Step 5: stop broker, increase page size
> cat my.broker.properties
> addressSettings."FOO".pageSizeBytes=4048576
> ...
> Step 6: run broker, observe logs show paging warning
> 2024-06-25 15:23:47,135 WARN [org.apache.activemq.artemis.core.server]
> AMQ224123: Address FOO has more pages than allowed. System currently has 1
> pages, while the estimated max number of pages is 0 based on the
> page-limit-bytes (1048576) / page-size (4048576)
