Major I have multiple instances of Ametys using the same solr server with different prefix.
One use the prefix ametys- an other use the prefix ametys-odf-
During initialisation, of the one with prefix ametys- I have the following warning in my log :
Message: Error when trying to update Ametys URL core property on Solr server. Location: org.apache.cocoon.util.log.SLF4JLoggerAdapter.warn(SLF4JLoggerAdapter.java:101) Thrown: java.lang.NullPointerException: Cannot invoke "org.apache.solr.client.solrj.SolrClient.request(org.apache.solr.client.solrj.SolrRequest, String)" because "client" is null at org.apache.solr.client.solrj.SolrRequest.process(SolrRequest.java:279) at org.ametys.cms.content.indexing.solr.SolrIndexer.updateAmetysUrlCoreProperty(SolrIndexer.java:424) at org.ametys.cms.content.indexing.solr.SolrCoreInit.updateAmetysUrlCoreProperty(SolrCoreInit.java:105) at org.ametys.cms.content.indexing.solr.SolrCoreInit.init(SolrCoreInit.java:70)
After investigation, it happens because we try to update the collection named odf-xxx because the method getCoreNames() returns every available core that starts with the prefix
