Description

A class defined as

@groovy.transform.AutoExternalize
class ClassUnderTest { 
    void writeExternal(ObjectOutput out) throws IOException { }
    void readExternal(ObjectInput oin) { }
}

Will override the definition of readExternal/writeExternal every single time.

In contrast with @Canonical for example where explicit toString() is not overridden.
