Hello, I observed the following change on switching from solr verion 6.4.2 to 6.6.2:
In 6.6.2, in case of an init failure, SolrCores.getCoreDescriptor does not return the core. The core is transient in nature but was not present in transient core cache. This was not the case in 6.4.2. I was getting the CoreDescriptor even in case of init failure. As a result of described behavior, unload of such a core (one with init failures) does not work properly. Thanks, Shefali
