Grails 4.0.11 GroovyConsole error with Gorm domain class

Question

The following test works in a Grails controller:

Domain class:

package freight

class CodeList {
    private static final long serialVersionUID = 1

    String codeType
    String code
    String description
  
    static constraints = {
        codeType nullable: false, blank: false
        code nullable: false, blank: false, unique: 'codeType'
        description nullable: true, blank: true
    }

    static mapping = {
    }
}  

Code in controller action:

def o = CodeList.get(10254)
println o as JSON  

Output:

{"id":10254,"code":"AFR","codeType":"AOC_CODE","description":"Africa"}  

When I try this in grails console I get this error:

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'freight.CodeList : 10254' with class 'freight.CodeList' to class 'freight.CodeList'
    at freight.CodeList.get(CodeList.groovy)
    at freight.CodeList$get.call(Unknown Source)
    at ConsoleScript1.run(ConsoleScript1:3)

What's wrong with this?

The following runs without error and gets the same row:

def row = CodeList.findById(10254)
def rows = CodeList.findAllWhere(id: 10254L) // println rows[0]

Alternative solution

I installed the Grails web-based Groovy console plugin and that works much better and faster than grails console. Wish I have found this sooner.
