We are trying to migrate from Helidon 2.5.4 to Helidon 3.2.0.
We have observed that some of our tests are failing with below error,
Caused by: org.hibernate.type.SerializationException: could not deserialize at org.hibernate.internal.util.SerializationHelper.doDeserialize(SerializationHelper.java:231) at org.hibernate.internal.util.SerializationHelper.deserialize(SerializationHelper.java:287) at org.hibernate.internal.util.SerializationHelper.clone(SerializationHelper.java:75) at org.hibernate.type.descriptor.java.SerializableJavaType$SerializableMutabilityPlan.deepCopyNotNull(SerializableJavaType.java:44) at org.hibernate.type.descriptor.java.SerializableJavaType$SerializableMutabilityPlan.deepCopyNotNull(SerializableJavaType.java:35) at org.hibernate.type.descriptor.java.MutableMutabilityPlan.deepCopy(MutableMutabilityPlan.java:45) at org.hibernate.type.descriptor.java.JavaType.getReplacement(JavaType.java:77) at org.hibernate.type.internal.ConvertedBasicTypeImpl.replace(ConvertedBasicTypeImpl.java:329) at org.hibernate.type.TypeHelper.replace(TypeHelper.java:88) at org.hibernate.event.internal.DefaultMergeEventListener.copyValues(DefaultMergeEventListener.java:493) at org.hibernate.event.internal.DefaultMergeEventListener.entityIsDetached(DefaultMergeEventListener.java:384) at org.hibernate.event.internal.DefaultMergeEventListener.onMerge(DefaultMergeEventListener.java:176) at org.hibernate.event.internal.DefaultMergeEventListener.onMerge(DefaultMergeEventListener.java:76) at org.hibernate.event.service.internal.EventListenerGroupImpl.fireEventOnEachListener(EventListenerGroupImpl.java:107) at org.hibernate.internal.SessionImpl.fireMerge(SessionImpl.java:828) ... 97 more Caused by: java.io.InvalidClassException: filter status: REJECTED

After further debugging, we noticed that exception is getting thrown(In ObjectInputStream) for the attribute which is of type java.net.URI We tried to fix this issue by applying @Basic annotation but still the error is same. Below are some of the attributes in the domain object which is getting used in the failed test case,
@Id
@Column(name = "ID")
@Basic
@JdbcTypeCode(SqlTypes.VARCHAR)
private UUID id;
@Column(name = "FILE_URI")
@Basic
@Convert(converter = UriAttributeConverter.class)
@Nullable
private URI fileUri;
@Nullable
@Column(name = "APPLICATION_URI")
@Basic
@Convert(converter = UriAttributeConverter.class)
private URI applicationUri;
Can someone please help us with this issue with any pointers?
