Re: disappearing MBeans
Sorry to reply to myself, but I just wanted to see if anyone saw this/had ideas why MBeans would be removed/re-added/removed. I tried looking for this in the code but was unable to grok what triggers bean removal. Any hints?

disappearing MBeans
I am using JMX to monitor my replication status and am finding that my MBeans are disappearing. I turned on debugging for JMX and found that solr seems to be deleting the mbeans. Is this a bug? Some trace info is below.. here's me reading the mbean successfully: Jan 27, 2011 5:00:02 PM ServerCommunicatorAdmin reqIncoming FINER: Receive a new request.
