Mark Miller commented on SOLR-9867:

Probably a problem with other examples too, but I have not looked into it.

> I first tracked this down to the fact that the run example tool is getting an error when
it tries to create the SolrCore and so it deletes the cores instance dir which leads to tlog
and index lock errors in Solr.
> The reason it seems to be trying to create the core when it already exists is that the
run example tool uses a core status call to check existence and because the core is loading,
we don't consider it as existing. I added a check to look for
> That seemed to let me start up, but my first requests failed because the core was still
loading. It appears CoreContainer#getCore  is supposed to be blocking so you don't have this
problem, but there must be an issue, because it is not blocking.
