title: eclipse - JPA entities from tables, no schemas listed
body: <p>I have a database (called "socializer") residing within MariaDB server and I'm trying to generate JPA entities from tables of that database in Eclipse, but cannot, because <a href="https://i.stack.imgur.com/2zXFp.png" rel="noreferrer">schema selection is grayed</a>. Any ideas why?</p>
  
  <p>My setup: Eclipse Neon, Eclipse Link 2.5.2, MariaDB 10.1.19-1, Arch Linux.</p>
  
  <p>I know that the connection to my database has been established, because I can see it <a href="https://i.stack.imgur.com/lFKFB.png" rel="noreferrer">listed in Data Source Explorer</a>, but its "Schemas" folder is displayed just empty, although it actually contains a few tables, created and perfectly observed within MySQL Workbench (the other listed databases appear to have empty "Schemas" as well).</p>
  
  <p>JDBC connection properties:</p>
  
  <pre><code>Database: "socializer"
  URL: "jdbc:mariadb://localhost:3306/socializer"
  User name: root
  Password: ""
  </code></pre>
  
  <p>JDBC driver (Generic JDBC Driver, mariadb-java-client-1.5.5.jar) properties:</p>
  
  <pre><code>Connection URL: "jdbc:mariadb://localhost:3306/socializer"
  Database Name: "socializer"
  Driver Class: "org.mariadb.jdbc.Driver"
  User ID: "root"
  </code></pre>
  
  <p>And yes, user name and password are ok (ping will fail if either of them is changed).</p>
