Description

StreamHandler (at "/stream") has several statically declared caches. I think this is problematic, such as in testing wherein multiple nodes could be in the same JVM. One of them is more serious – SolrClientCache which is closed/cleared via a SolrCore close hook. That's bad for performance but also dangerous since another core might want to use one of these clients!
