Bug on Message Listener?

Hello, there!

I've just found what seems to be an MII 12.0 bug.

I have tried to post 100 messages almost at the same time to the XMIIMESSAGELISTENER.

They were received and processed aparently sucessfully.

But when I try to access those messages contents I see that some of them were received "twice" and some were not received at all.

The message count is 100, as it should be.

Checking the XMII_JCOMESSAGES table I see that the messages that appear twice have the same received date.

I have already checked the client (which is a simple MII transaction doing HTTP Posts on a loop) and it is sending all the messages correctly.

It looks like an implementation bug, possibly due to multithreading issues inside MII.

Has anyone experienced something like that?

If it's really a bug, how can I report it to SAP?

Thanks in advance!
