>          Issue Type: Improvement
>          Components: Broker, Configuration
>    Affects Versions: 2.19.0
>            Reporter: Gary Tully
>            Priority: Major

> Currently for force paging on an address, for a DLQ for example, you would set
>  <address-full-policy>PAGE</address-full-policy>
>     <max-size-bytes>1</max-size-bytes>
> MaxSizeBytes  to some small number but the broker will complain with:
> 2021-11-15 16:21:51,606 ERROR [org.apache.activemq.artemis.core.server] 
> AMQ224000: Failure in initialisation: java.lang.IllegalStateException: 
> java.lang.IllegalStateException: pageSize for address DLQ.mytest >= maxSize. 
> Normally pageSize should be significantly smaller than maxSize, ms: 1 ps 1024
> You go ahead and downsize the page-size-bytes but don't want to cripple 
> de-page or page-in and use a reasonable value and some memory!
>  <address-full-policy>PAGE</address-full-policy>
>     <max-size-bytes>256</max-size-bytes>
>     <page-size-bytes>128</page-size-bytes>
> It should be sufficient to set:
>    <address-full-policy>PAGE</address-full-policy>
>    <max-size-bytes>0</max-size-bytes>
