我在Windows 7 PC上运行Rendezvous。我运行了Tibco提供的C ++示例代码，实现了一个简单的认证消息发送者（cmsender.cpp）和一个经过认证的消息监听器（cmlistener.cpp）。
原则上，运行这两个程序的结果似乎是发送者发送10条消息，而监听器应该接收10条消息并明确确认每条消息都已收到。但是，在输出中看起来并不正确：
发件人输出：
Publishing 10 certified messages on subject cm.test.subject
Publishing message: {index=1}
Publishing message: {index=2}
Confirmed message with seqno=2
Publishing message: {index=3}
Confirmed message with seqno=3
Publishing message: {index=4}
Confirmed message with seqno=4
Publishing message: {index=5}
Confirmed message with seqno=5
Publishing message: {index=6}
Confirmed message with seqno=6
Publishing message: {index=7}
Confirmed message with seqno=7
Publishing message: {index=8}
Confirmed message with seqno=8
Publishing message: {index=9}
Confirmed message with seqno=9
Publishing message: {index=10}
Last sequence number to be confirmed = 10
Confirmed message with seqno=10
监听器输出：
Listening on subject: cm.test.subject
Received message: {index=1}
status=Item not found, seqno=0
Received message: {index=2}
status=Success, seqno=2
Confirming message with seqno=2
Received message: {index=3}
status=Success, seqno=3
Confirming message with seqno=3
Received message: {index=4}
status=Success, seqno=4
Confirming message with seqno=4
Received message: {index=5}
status=Success, seqno=5
Confirming message with seqno=5
Received message: {index=6}
status=Success, seqno=6
Confirming message with seqno=6
Received message: {index=7}
status=Success, seqno=7
Confirming message with seqno=7
Received message: {index=8}
status=Success, seqno=8
Confirming message with seqno=8
Received message: {index=9}
status=Success, seqno=9
Confirming message with seqno=9
Received message: {index=10}
status=Success, seqno=10
Confirming message with seqno=10
请注意，在发送方输出中，永远不会确认seqno = 1的消息。此外，在侦听器输出中，找不到seqno = 0的消息。 （我稍微修改了Tibco cmlistener.cpp示例代码以打印出状态和seqno值，以进行故障排除，但除此之外，代码仍然是原样。）
是否有人使用此Rendezvous示例代码知道这是否是预期的行为？为什么没有确认seqno = 1的消息？为什么听众没有看到seqno = 1的消息？为什么seqno = 0的消息导致状态为＆＃34;找不到项目＆＃34;？
