> While testing my patch for SOLR-4629, i noticed a really random error that i traced back
to the core reload (do to config file replication) failed because the directory was locked.
> From what i can tell, the lock checking code in the SolrCore constructor isn't even suppose
to be used in the reload situation where there is a "prev" core, except that in SolrCore.reload
there is this check...

>     if (!getNewIndexDir().equals(getIndexDir())) {
>       // the directory is changing, don't pass on state
>       prev = null;
>     }
> {noformat}
> ..i'm not really sure i understand this logic, or what exactly the source of the problem
is, or if the lock checking code should just be changed to work a differnet way completley,
but it seemed worthy of tracking in it's own jira.
> log details to follow
