> We are using 0.10.2.0 (but this is reproducible even with 0.10.2.1 and latest 
> upstream) in our environments. Our topic names contain (one or more) dot 
> characters in their name. So we have topics like {{foo.bar-testtopic}}. Topic 
> deletion is enabled on the broker(s) and our application does delete the 
> topics as and when necessary.
> We just ran into a case today where for some reason the Kafka broker had 
> either to be taken down (or went down on its own). Some of the topics which 
> were deleted (i.e. a deletion marker folder was created for them) were left 
> around after Kafka broker had gone down. So the Kafka logs dir had 
> directories like 
> {{foo.bar-testtopic-0.bb7981c216b845648edfe6e2b0a5c050-delete}}.
> When we restarted the Kafka broker, it refused to start and kept shutting 
> down and running into this exception:
> {code}
> [2017-05-12 21:36:27,876] ERROR There was an error in one of the threads 
> during logs loading: java.lang.StringIndexOutOfBoundsException: String index 
> out of range: -1 (kafka.log.LogManager)
> [2017-05-12 21:36:27,900] FATAL [Kafka Server 0], Fatal error during

> The only way we could get past this is pointing Kafka broker to a different 
> Kafka logs directory which effectively meant a lot our topics were no longer 
> accessible to the application.
