docs: <p>This method is used to clean up a connection before it is returned to the connection
  pool for later reuse. WebSphere automatically resets all standard connection
  properties (fields for which getters and setters are defined on
  <code>java.sql.Connection</code>).
  This method can be used to reset other properties proprietary to a specific
  JDBC driver/database, preparing the connection for
  reuse.</p>
  
  <p>Use the provided connection to create
  and execute statements for the purpose of cleaning up the connection. Any statements
  created within the <code>doConnectionCleanup</code> method must be explicitly closed
  within the <code>doConnectionCleanup</code> method. The
  <code>doConnectionCleanup</code> method must never close the
  connection being cleaned up.</p>
  
  <p>If <i>any</i> standard connection properties are modified in this method, a value
  of true must be returned, indicating to WebSphere that at least one standard
  connection property was modified. A value of false should be returned only if
  <i>no</i> standard connection properties were modified.</p>
  
  @param conn the connection to attempt to cleanup.
  @return true if <i>any</i> standard connection property was modified, otherwise false.
  @exception SQLException if an error occurs while cleaning up the connection.
