Geode spring boot Cache Client Updater Thread crash

Question

Using

implementation 'org.springframework.geode:spring-geode-starter:1.2.8.RELEASE'    
implementation 'org.springframework.data:spring-data-geode:2.2.8.RELEASE'

I setup a listener

@Service
public class LQuote extends CacheListenerAdapter {
...afterCreate...
...afterUpdate...
}

When an event comes to the local cache from the server the Cache Client Updater Thread reads the event using readPdxSerializable pdxType but when it is trying to load the domain object class it hits an endpoint Crashed issue:

I guess this could be because the domain object class does not override ToData and FromData or FromPdx and ToPdx according to Implementing PdxSerializable but adding these, or adding

@Region
public class Quote implements DataSerializable {

with toData and fromData has no effect. The issue remains.

Answer 1

The way to resolve this was, like, to specify domain objects for all the objects that I want to use.

class myObject1 implements PdxSerializable {

...

public void toData(PdxWriter writer)
{
    writer.writeString("MsgType", MsgType);
    ...
}

public void fromData(PdxReader reader)
{
    MsgType = reader.readString("MsgType");
    ....
}
