-------------------------------------
The patch above is against the 7.3 branch. I have not yet checked whether it
will apply cleanly to master.
> SolrCLI can swallow all information about an exception from a request to Solr

> User got an NPE when trying to create a core, no useful information:
> {code}
> $ /usr/local/solr/bin/solr create -V -c new_core
> WARNING: Using _default configset with data driven schema functionality.
> NOT RECOMMENDED for production use.
> To turn off: bin/solr config -c new_core -p 8983 -property
> update.autoCreateFields -value false
> Exception in thread "main" java.lang.NullPointerException

> {code}
> Looking at the code, this happened because SolrCLI got a
> ClientProtocolException in its call to HttpClient, but that exception did NOT
> have a message string attached, so when the code in the catch block tried to
> look at the message, it threw NPE.
