Major Description
In SOLR-8642, hyphens are no longer considered valid identifiers for cores (and collections?). Our solr instance was successfully using hyphens in our core names, and our affected cores now error with:
marc-profiler_shard1_replica1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Invalid name: 'marc-profiler_shard1_replica1' Identifiers must consist entirely of periods, underscores and alphanumerics
Before starting to rename all of our collections, I wonder if this decision could be revisited to be backwards compatible with previously created collections.
