Andrew Bennison commented on SOLR-9179:
---------------------------------------
I replaced contrib and dist directories with 6.0.1 versions and replaced webapp
with 6.0.1 version.
Updated solrconfig to reflect new version ie lucene version from 6.0.0 to 6.0.1
We use ClassicSchema on current 5.x Production and 6.0.0 Development Versions
With Schema set at classic get the initialization Error as soon as I start
everything up.
If I replace <schemaFactory class="ClassicIndexSchemaFactory"/> with
<schemaFactory class="ManagedIndexSchemaFactory">
<bool name="mutable">true</bool>
<str name="managedSchemaResourceName">managed-schema</str>
</schemaFactory>
Then when I load it creates the managed-schema and loads the core.
If I then shutdown and restart I get the Error.
If I rename schema.xml.bak to schema.xml and delete managed-schema it will load
again OK.
everything is fine running under 6.0.0
