title: Java 11 migration - createConnectionBuilder() from PoolDataSourceImpl clashes with createConnectionBuilder() from javax.sql.DataSource
body: <p>I am trying to migrate a project from Java 8 to Java 11, which uses ojdbc. I am using a class which extends PoolDataSourceImpl, which implements PooLDataSource, which extends javax.sql.DataSource and while trying to built it with maven it gives this error:</p>
  
  <blockquote>
    <p>Compilation failure
    [ERROR] createConnectionBuilder() in oracle.ucp.jdbc.PoolDataSourceImpl cannot implement create
    ConnectionBuilder() in javax.sql.DataSource
    [ERROR]   return type oracle.ucp.jdbc.UCPConnectionBuilder is not compatible with java.sql.ConnectionBuilder</p>
  </blockquote>
  
  <p>Does anyone have any suggestions?</p>
