title: JDBC Connection close vs abort
body: <p>I asked this question (<a href="https://stackoverflow.com/questions/51752254/how-do-i-call-java-sql-connectionabort?noredirect=1#comment90464797_51752254">How do I call java.sql.Connection::abort?</a>) and it led me to another question.</p>
  
  <p>With </p>
  
  <pre><code>java.sql.Connection conn = ... ;
  </code></pre>
  
  <p>What is the difference between</p>
  
  <pre><code>conn.close();
  </code></pre>
  
  <p>and </p>
  
  <pre><code>conn.abort(...);
  </code></pre>
  
  <p>?</p>
