docs: The method is called from the transaction (manager) to check if the XA
  resource is the same as the given XA resource in the parameter
  <code>_xaras</code>. This is done with a string compare
  (method {@link String#equals(Object)}) off the
  {@link Object#toString()} methods of this and the XA resource in
  <code>_xaras</code>.
  
  @param _xares    XA resource used to test if same resource
  @return <code>true</code> if the string compare returns that they are
  equal, otherwise <code>false</code> is returned
