Gregory Chanan updated SOLR-7967:
---------------------------------
    Description: 
SOLR-7742 introduced Immutable ConfigSets.  There are checks added to 
SolrConfigHandler and SchemaHandler so that if a user tries to modify the 
SolrConfig or the Schema via either of these interfaces an error is returned if 
the ConfigSet is defined to be immutable.

Updates to the schema made via the AddSchemaFieldsUpdateProcessorFactory are 
not checked in this way.  I'm not certain this should be considered a bug.  A 
ConfigSet is defined by \{SolrConfig, Schema, ConfigSetProperties\}.  On one 
hand, you can argue that you are modifying the Schema, which is part of the 
ConfigSet, so the immutable check should apply. On the other hand, the 
SolrConfig (which defines the AddSchema...Factory} defines that it wants the 
Config to be updated, so if you view the ConfigSet in totality you could argue 
nothing is really changing. I'd slightly lean towards adding the check, but 
could go either way.

Other opinions?
