Serialization exceptions on application which uses hazelcast and subzero and is deployed on 2 Weblogic nodes
Given I register classes for serialization using SubZero
private void setupSerialization(final Config config) {
config.getSerializationConfig()
.setEnableCompression(true);
SubZero.useForClasses(config, GetApplicationDataRequest.class, GetApplicationDataResponse.class);
}
public class GetApplicationDataRequest {
protected String applicationCode;
protected List<ApplicationDataSet> dataSet;
// getters, setters, equals, hashcode, empty constructor, all args constructor
}
and when I deploy application to 2 weblogic nodes which form hazelcast cluster using tcp ip protocol,
I am sometimes getting exceptions

Very weird part of these stacktraces is java.lang.ClassNotFoundException: et.mihalcin.ApplicationDetail^A^@^A^A\ where first character of class name is missing and suffix is some random characters.
Please note, it doesn't occur consistenly. It sometimes manifests, sometimes not.
Do you know why this happens?
Can it be something wrong with this library?
