Tomás Fernández Löbbe commented on SOLR-4218:
---------------------------------------------
bq. I don't see this exception when running from Eclipse.
Forget about that, I had a slightly outdated revision in Eclipse.
Seems to me that this issue was introduced by the changes in SOLR-4204, looks
like the ShardHandler may not be initialized under some conditions and that's
why some of it fields are null.
