Solr SSL errors with Alfresco

I have Solr running and configured to use the ssl-repo-client.keystore and ssl-repo-client.truststore files that I generated in PKCS12 format. I'm able to access the Solr web page successfully, however errors are being logged. I've attached my configurations and error logs below. Has anybody run into this issue? My search services are (obviously) not working. I was able to check the files using keytool and they seem to be fine. Is there some configuration that I'm missing?

solr.in.cmd:
set SOLR_SSL_KEY_STORE=D:\alfresco-content-services\solr\solrhome\keystore\ssl-repo-client.keystore
set SOLR_SSL_KEY_STORE_PASSWORD=mypassword
set SOLR_SSL_KEY_STORE_TYPE=PKCS12
set SOLR_SSL_TRUST_STORE=D:\alfresco-content-services\solr\solrhome\keystore\ssl-repo-client.truststore
set SOLR_SSL_TRUST_STORE_PASSWORD=mypassword
set SOLR_SSL_TRUST_STORE_TYPE=PKCS12
set SOLR_SSL_NEED_CLIENT_AUTH=true
set SOLR_SSL_WANT_CLIENT_AUTH=true

solrcore.properties:
alfresco.encryption.ssl.keystore.type=PKCS12
alfresco.encryption.ssl.keystore.provider=SUN
alfresco.encryption.ssl.keystore.location=D:/alfresco-content-services/solr/solrhome/keystore/ssl-repo-client.keystore
