> Invalid topics prevent broker start-up

> Key: KAFKA-104
> URL: https://issues.apache.org/jira/browse/KAFKA-104
> Project: Kafka
> Issue Type: Bug
> Reporter: Joel Koshy
> Priority: Minor

> 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.
