Alexey Ponomarenko commented on SOLR-12060:
-------------------------------------------

Hi [~erickerickson]  thanks for reply. As for me it is also a code issue 
because it is not informative message how can I resolve configuration issue. I 
think it is need to be at least some message what is wrong because it can send 
a lot of time investigating what is wrong and how to fix it. 

I think that more informative message should be shown rather just "Null Pointer 
exception".

What do you think?
