    Sample API to create a core is as mentioned below.

    http://localhost:8983/solr/admin/cores?action=CREATE&name=coreName&instanceDir=path/to/dir
&config=config_file_name.xml&dataDir=data

    Using SolrJ API it would be someting like as below.

      String solrUrl = "http://localhost:8983/solr";
  HttpSolrClient client = new HttpSolrClient.Builder(solrUrl).build();

  CoreAdminRequest.Create createCore = new CoreAdminRequest.Create();
  createCore.setCoreName(core);
  createCore.setConfigSet( coreName);
  createCore.process(client);

    I had the same issue, somehow it is related to openJDK. I installed oracleJDK and set it as default java using 

    update-alternatives --config java

    and selected oracleJDK home as default then used

    solr create -c myCore

    It worked for me.
