A general solution for JDK-8311071 may be new API to clean up and restore archived Java objects. 

For example, something like this can be used:

- dump time: remove SoftReferences before the object is archived
- run time: recreate the SoftReferences after the object is materialized

class LambdaFormEditor$Transform implements CDSCleaner, CDSRestorer {
    Object cache;

    private Transform(long packedBytes, byte[] fullBytes, LambdaForm result) {
        cache = new SoftReference<LambdaForm>(result);
        this.packedBytes = packedBytes;
        this.fullBytes = fullBytes;
        CDSCleaner.register(this);
    }

    public void cleanForCDS() { // CDSCleaner
        SoftReference<LambdaForm> ref = (SoftReference<LambdaForm>)cache;
        cache = ref.get();
    }

    public void restoreFromCDS() { // CDSRestorer
        cache = new SoftReference<LambdaForm>((LambdaForm)cache);
    }
}
