Description
Creating a Managed Stopwords list that has the same name as a previously deleted list results in an error if the core has been reloaded after deleting the list. Going through the same flow with Managed Synonyms doesn't result in this unexpected behaviour.
On a newly started standalone Solr with the techproducts core:
curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
The second PUT request results in a status 500 with error msg "java.util.LinkedHashMap cannot be cast to java.util.List".

Similar requests for synonyms work fine, no matter how many times I repeat the CREATE/DELETE/RELOAD cycle:
curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}' \ http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}' \ http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
Reloading after creating the Stopwords list but not after deleting it works without error too on a fresh techproducts core (you'll have to remove the directory from disk and create the core again after running the previous commands).
curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
And even curiouser, when doing a CREATE/DELETE for Stopwords, then a CREATE/DELETE for Synonyms, and only then a RELOAD of the core, the cycle can be completed twice. (Again, on a freshly created techproducts core.) Only the third attempt to create a list results in an error. Synonyms can still be created and deleted repeatedly after this.
curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}' \ http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}' \ http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap curl -X DELETE http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts curl -X PUT -H 'Content-type:application/json' --data-binary \ '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \ http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
The same successes/errors occur when running each cycle against a different core if the cores share the same configset.
