Error message: Can not set Integer field to java.lang.Class

Question

I was running in some strange error message while defining a domain-model in Grails and applying a constraint to an integer variable.

package example

class Ip {

String inetAddress
String DNS
Integer Points


String toString(){
    "${inetAddress}"
}

static constraints = {
    inetAddress()
    DNS()
    Points(nullable: true)

  }

}

This created the following error message when starting the application

 Message:Can not set org.springsource.loaded.ISMgr field example.Ip.r$fields to java.lang.Class

Changing the variable definition from

 Integer Points

to

 Integer points

solved the problem.

seems that "Points" is handled as an object and "points" as a property value. And objects are not allowed to be null
