[jira] [Commented] (CASSANDRA-3797) StorageProxy static initialization not triggered until thrift requests come in

["Peter Schuller (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-3797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13194531#comment-13194531 ] 

Peter Schuller commented on CASSANDRA-3797:
-------------------------------------------

Maybe a Class.forName() is cleaner (a Class klass = StorageProxy.class does not (necessarily) cause it to be loaded).

> While plugging in the metrics library for CASSANDRA-3671 I realized (because the metrics library was trying to add a shutdown hook on metric creation) that starting cassandra and simply shutting it down, causes StorageProxy to not be initialized until the drain shutdown hook.
> Effects:
> * StorageProxy mbean missing in visualvm/jconsole after initial startup (seriously, I thought I was going nuts ;))
> * And in general anything that makes assumptions about running early, or at least not during JVM shutdown, such as the metrics library, will be problematic
