In order to retrieve metadata on received messages, such as the publisher of a sent message, ros provides MessageEvents ([1]). This would also be desireable for rosjava.

Actually it is not a "Defect", but a suggestion for an "Enhancement". Didn't find how to change that.

I'm just in the trouble of the MessageEvent, because I need to write ros bag in my app. And I'm trying to apply the jrosbag to my app, however the jrosbag need the meta data of the message which topic is subscribed.

I had ask this question in stackoverflow, but it's seems no result.
