Guido commented on SOLR-7451:
-----------------------------
Hello. I am not sure why this is so dangerous (surely you know it better than
me). I would be happy if you want to elaborate it. Anyway, I believe that the
problem is strictly related to a plugin inside the /lib/ directory: as a second
test, I tried to modify my solrconfig to avoid the use of the custom plugin and
I was able to create the collection. Then, I deployed the plugin inside the
'lib' directory, modified the solrconfig and reloaded the collection. In this
way I did not get the problem. I hope that this helps you: I always get
problems while trying to create a collection which uses a custom plugin and
this 2-steps always helps me.
