Colin B. commented on KAFKA-104:
--------------------------------

I am unable to reproduce this issue.

It is likely this was fixed in another issue such as: https://issues.apache.org/jira/browse/KAFKA-495

> Excerpt from a trace we saw today. If there is a topic directory with an invalid name, then the registerMBean call throws an exception which eventually results in a start failure. Also, if you try sending messages with an invalid topic to a broker, the broker's logs get flooded with these exceptions. Easy fix is to wrap the registerMBean with Utils.swallow; and probably prevent ProducerRequest from accepting invalid topics.
