when sending a large message in openwire, we will read the entire file on the memory, make the conversion from core, and send it on net throughOpenWireProtocolManager::sendPhisical.

Such allocation should be limited and be sent in chunks.

The reason for this is that the following may be observed with sending large messages via openwire:

[org.apache.activemq.artemis.core.client] AMQ212037: Connection failure to /127.0.0.1:45338 has been detected: Direct buffer memory [code=GENERIC_EXCEPTION]
