Trying to migrate from Corda V1 to V3. It was working fine in V1 but after using Corda V3 its throwing below error -

java.util.concurrent.ExecutionException: java.io.NotSerializableException: net.corda.core.contracts.TransactionState -> data(net.corda.core.contracts.ContractState) -> Defined setter for parameter eligibleCurrency takes parameter of type interface java.util.List yet underlying type is java.util.List -> class com.xxx.agreementnegotiation.state.AgreementNegotiationState

Some part of my state

public class AgreementNegotiationState extends AgreementStateTemplate implements QueryableState {
private String baseCurrency;
private List<String> eligibleCurrency;
private int deliveryAmount;

public String getBaseCurrency() {
    return baseCurrency;
}

public void setBaseCurrency(String baseCurrency) {
    this.baseCurrency = baseCurrency;
}

public List<String> getEligibleCurrency() {
    return eligibleCurrency;
}

public void setEligibleCurrency(List<String> eligibleCurrency) {
    this.eligibleCurrency = eligibleCurrency;
}

public int getDeliveryAmount() {
    return deliveryAmount;
}

public void setDeliveryAmount(int deliveryAmount) {
    this.deliveryAmount = deliveryAmount;
}

}

Please assist.

This is a bug in Corda 3. It will be fixed in Corda 4.

In the meantime, the workaround is to change eligibleCurrency to a List<?>, and cast its elements as required:

private List<?> eligibleCurrency;

public List<?> getEligibleCurrency() {
    return eligibleCurrency;
}

public void setEligibleCurrency(List<?> eligibleCurrency) {
    this.eligibleCurrency = eligibleCurrency;
}

Thanks but now im getting -net.corda.testing.node.internal.ListenProcessDeathException: The process that was expected to listen on localhost:10000 has died with status: 1. Please respond on stackoverflow.com/questions/49813946/… . I have added my question as well

As per corda V3 , Collections are immutable so you cannot add to the existing collection.The Solution is create a function which take the copy of the existing collection and add the item in it and finally referenced it to the eligibleCurrency list.

private Collection<SupportingDocument> supportingDocs;
public void addSupportingDoc(SupportingDocument supportingDoc) {

    //since corda 3.1 has unmodifiable collection
    List<SupportingDocument> suppDoc = new ArrayList<SupportingDocument>();
    for(SupportingDocument existingDoc : supportingDocs){
        suppDoc.add(existingDoc);
    }
    // adding new document
    suppDoc.add(supportingDoc);
    this.supportingDocs = Collections.unmodifiableCollection(suppDoc);
}

I hope , it makes sense
