Hi,

I have been using nightly builds of Solr 1.3 with SolrJ for some time now.  I 
upgraded the Solr jars from the 14-Aug nightly and my program would not 
compile.  I found that SolrCore constructor needed a new parameter 
CoreDescriptor.  I passed null and it worked fine.

I then upgraded to the Solr jars from the 20th-Aug nightly and it started 
throwing NullPointerExceptions.  My guess is that the addition of the method 
SolrCore.getStatistics() which has the line "lst.add("aliases", 
getCoreDescriptor().getCoreContainer().getCoreNames(this));" throws the NPE.

I searched the wiki and there is no mention of CoreDescriptor there.  Could 
somebody please explain what CoreDescriptor is all about and how it is supposed 
to be used?

Thanks,
Nikhil
