我已经将我的应用程序从Grails-3.x迁移到Grails-4.1.1。我的大多数Domain类都实现了以下Traits类（DynamicProperties），由于某种原因，该类实现了GormEntity-以覆盖propertyMissing方法。

trait DynamicProperties<D> implements GormEntity<D> {

def dynamic = [:]

def propertyMissing(String name, value) {
    if (!propertyIsDatasource(name)) {
        dynamic[name] = value
    }
}

def propertyMissing(String name) {
    if (propertyIsDatasource(name)) {
        super.propertyMissing(name)
    } else {
        dynamic[name]
    }
}

boolean propertyIsDatasource(String name) {
    false
} 
}

上述特征已经由许多类似的域类实现

class Customer implements DynamicProperties<Customer> {

String customerCode
String customerName
Address address
....
}

现在，当我运行应用程序时，它抛出以下异常

HHH000142: Bytecode enhancement failed: com.apps.billing.Customer.

它以前在Grails3.x中运行良好
