Description

Steps to reproduce the problem:
1) Start a master Solr instance (called A)
2) Start a Solr instance with replication handler configured, but with no "slave" configuration. (called B)
3) Issue the request http://B:port/solr/replication?command=fetchindex&masterUrl=http://A:port/solr/replication
4) While B is fetching the index, issue the request: http://B:port/solr/replication?command=details

Expected behavior: See the replication details as usual.

Getting an exception instead:
