Description
In Wildfly 10,
We have some system tests that sporadically fail when the client of the application loads an entity, connected to other sub-entities, where one of these sub-entities has a @Transient field.
In Particular, we have an entity Attributes that has a field of the form:
@Transient
private Map<String, String> attributeMap = new TreeMap<String, String>();
The root cause of the deserialization problem is of the form:
Caused by: an exception which occurred:
in object of type java.util.TreeMap
in field attributeMap
in object of type basepackage.entity.Attributes
in field attributes
in object of type basepackage.entity.SubEntityB
in element at index [0] of size [1]
in field delegate
in object of type org.eclipse.persistence.internal.indirection.jdk8.IndirectList
in field loadUnits
in object of type basepackage.entity.ParentEntityA
The de-serialization execution stack looks as follows:
Caused by: java.io.OptionalDataException

Currently no sample application exists to reproduce the issue.
On weblogic the deserialization process goes without incident.
Could the @Transient annotation and the eventual (empty map vs popuated attribtues map) play a role on this issue?
Kindest regards.
