Grails 3.3.9: Unable to inherit hasMany property

[JitinD]

I'm currently migrating my grails code from version 2.5.6 to 3.3.9. On 3.3.9, I observed this weird behaviour.

There's an abstract class (in src/main/groovy) which contains a hasMany relationship.

package srcFolder

import grailsthree.TestSimpleClass

abstract class TestSuperClass {
    String superClassValue

    static hasMany = [simples: TestSimpleClass]
}

A domain class which inherits this abstract class.

package grailsthree

import srcFolder.TestSuperClass

class TestSubClass extends TestSuperClass{
    String subClassValue

    static constraints = {
    }
}

In the Bootstrap, call the addTo on the hasMany property of subclass,

package grailsthree

class BootStrap {

    def init = { servletContext ->
        TestSimpleClass testSimpleClass = new TestSimpleClass(simpleClassValue: 'simpleClassValue').save()
        TestSubClass testSubClass = new TestSubClass(subClassValue: 'subClassValue')
        testSubClass.addToSimples(testSimpleClass)
        testSubClass.save()
    }
    def destroy = {
    }
}

Got following error:

groovy.lang.MissingMethodException: No signature of method: grailsthree.TestSubClass.addToSimples() is applicable for argument types: (grailsthree.TestSimpleClass) values: [grailsthree.TestSimpleClass : 1]

Seems like on Grails 3.3.9, the sub-class is not inheriting the abstract class hasMany property. This is working fine for Grails 2.5.6.

Expected Behaviour

The child sub-domain class should've inherited the hasMany relationship from the abstract class.

Actual Behaviour

The child sub-domain class doesn't inherit the hasMany relationship from the abstract class.

Environment Information

• Operating System: Ubuntu 16.04
• Grails Version: 3.3.9
• JDK Version: 1.8.0_201

As a workaround, I've converted the above-mentioned src/main/groovy classes into domain classes, and I've added static mapWith block set to "none" to make sure they're not persistable.
