PageCursorProviderImpl::cleanup can save decoding pages without large messages
URL: https://github.com/apache/activemq-artemis/pull/3044#issuecomment-606911209
I could fix the rebasing, however your implementation is not valid.
Up until CoreMessages, we used a special record type on paging, only used
for Large Messages.
With AMQP, I didn't use that record at all. instead I used the Persister
from the AMQP Protocol. So, you would have to check the Persister Type, ad the
proper record position.
Besides, the following implementation is not self documented... if things
change this will likely introduce bugs (lack of encapsulation of this rule):
```
public static boolean isLargeMessage(ActiveMQBuffer buffer) {
// skip transactionID
final boolean isLargeMessage = buffer.getByte(buffer.readerIndex() +
Long.BYTES) != 0;
return isLargeMessage;
}
```
You would need to encapsulate this through PagePosition for Core Records, or
check the Persister, and do the proper encapsulation if you really want to
implement such feature.
