[jira] [Comment Edited] (SOLR-13661) A package management system
for Solr

bq. Then you need a restart of the app to be sure that the new/changed jars gets loaded, due to how the Java class loaders work.
I think Noble addressed exactly this part in his recent work; plugins can be hot loaded (in their isolated classloaders) without needing a node restart or a core reload. I am very impressed by what I see in master.
That work, along with the PF4J for discovery, repository, dependency etc. should make for a very cool overall solution. Once I finish some work on SOLR-13662 (PF4J), I'll document the workflows in our ref-guide.
