The problem is the following, I needed to implement the CRUD, It's was about ten class and I did not want to implement for all the same code that get request values and set in each property.
So, I remembered the Bind Class from Form. After of some searchs, I did find this method:

    function PopulateWithRequest($obj = NULL) {
        if (!is_object($obj)) {
            $obj = new StdClass ();
        }

        foreach ($_REQUEST as $var => $value) {
            //Set Value
            $obj->$var = trim($value); //here you can add a filter, like htmlentities ...
        }

        return $obj;
    }

I put this method in base class and after I used like this:

    $entity = new Entity();
    $entity = $entity->PopulateWithRequest($entity);

I know that today exists Zend Framework, CodeIgniter, Laravel, CakePHP and several others, but the system that I was working was old and does not compensate reimplement everythink.

  manager.PasswordValidator = new PasswordValidator
            {
                RequiredLength = 6,
                RequireLowercase = true,
                RequireDigit = false,
                RequireUppercase = false
            };  

How to change the same configuration in MVC 6?

Simple!

The Solution Beta6

In the Startup.cs write the code:

services.ConfigureIdentity(options =>  
{
    options.Password.RequireDigit = false;
    options.Password.RequiredLength = 6;
    options.Password.RequireLowercase = false;
    options.Password.RequireNonLetterOrDigit = false;
    options.Password.RequireUppercase = false;
});

The Solution after Beta8

// Add Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>(options =>  
{
    options.Password.RequireDigit = false;
    options.Password.RequiredLength = 6;
    options.Password.RequireLowercase = false;
    options.Password.RequireNonLetterOrDigit = false;
    options.Password.RequireUppercase = false;
})
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();

Well, thank God that the "heap space" in Java is configurable. But, how to do this only in the Pentaho?

Simple!!!
The solution is: edit the sponn (.bat or .sh) and change the variable PENTAHODIJAVA_OPTIONS.
By default, this variable have the value "-Xmx512m" means 512Mb of space. So just you set "-Xmx2g" to change the heap space for 2Gb.
