Saving a domain object in grails

Question

I can't save the domain objects in grails on Windows 8.1 and Centos 7. Whenever I try to create an empty domain class and save it in BootStrap.groovy, I'm always getting the same error message after running the application:

Error |

My domain class:

package com.test

class Book {
    String name
    static constraints = {
    }
}

BootStrap.groovy:

import com.test.Book
class BootStrap {

    def init = { servletContext ->
        new Book(name: "My Book").save()
    }
    def destroy = {
    }
}

I tried with both 2.4.3 and 2.4.4 versions of grails. My jdk version is 1.7.0_71 (Tried with jdk6 and jdk8, too). The interesting is, I tried the exact steps on Ubuntu and OpenSuse and I've managed to save the object without problem. So, what can be the problem?

The problem is solved. It seems grails have problems with language packages of the Operating System. I was using Turkish language pack of Windows and Centos. Now I've changed it to English and the problem is solved.
