hi Justin, I am using version - apache-artemis-2.4.0. and for the Java dependency i am importing "*org.apache.activemq:artemis-core-client:2.2.0*"
<http://activemq.2283324.n4.nabble.com/file/t378513/Screen_Shot_2018-03-15_at_8.png> as you can see above the, Packet which is cast to the type SessionSendMessage has a getMessage() implementation which has the return Type of the implementation of the Interface ICoreMessage When in my IntelliJ i click to navigate to where the implementation is it takes me to the below class. import org.apache.activemq.artemis.api.core.ICoreMessage; import org.apache.activemq.artemis.core.protocol.core.impl.PacketImpl; public abstract class MessagePacket extends PacketImpl implements MessagePacketI { protected ICoreMessage message; public MessagePacket(final byte type, final ICoreMessage message) { super(type); this.message = message; } @Override public ICoreMessage getMessage() { return message; } @Override public String getParentString() { return super.getParentString() + ", message=" + message; } } The interface ICoreMessage has multiple implementations as seen below <http://activemq.2283324.n4.nabble.com/file/t378513/Screen_Shot_2018-03-15_at_8.png> Now the copy Method is being picked up from one of the two implementations (ClientMessageImpl or CoreMessage) as shown below <http://activemq.2283324.n4.nabble.com/file/t378513/Screen_Shot_2018-03-15_at_9.png> The getBuffer() method is in CoreMessage implementation, whose return type is ByteBuf (io.netty.buffer.ByteBuf) Please let me know if i missed any details or if am wrong.
