A user's decision service deployed on KIE server receives REST commands from client,
MarshallingException due to class loading failure occurs during JSON unmarshalling before
the commands are processed. I attached a simplified reproducer reproducer_02699633_1.zip
expressing the issue, and the error message is like below:
{noformat}
Caused by: com.fasterxml.jackson.databind.exc.InvalidTypeIdException: Could not resolve
type id 'com.example.reproducer.common.params.ContactParam' as a subtype of
[simple type, class com.example.reproducer.common.base.IRuleParam]: no such class found

"commands" : [ { "insert" : { "object" : {
"com.example.reproducer.common.base.Fact1": { "parameter" : {

"com.example.reproducer.common.params.ContactParam",
"contactInfo" : 123456789 } } } } }, {
"fire-all-rules" : "" } ]}"; line: 1, column: 185] (through
reference chain:

{noformat}
For full error messages, see full_error_messages.txt in Attachment.
The user's decision service (kjar) uses classes in another module jar as a library.
ContactParam class which is a sub type of IRuleParam interface is in the kjar and
IRuleParam interface is in the module jar.
Also, @JsonTypeInfo(use = Id.CLASS) annotation is given to IRuleParam like below in
order for JSON implementation to recognize a given class to Fact1.parameter as a sub type
of IRuleParam.
{code:java}
@JsonTypeInfo(use = Id.CLASS)
public interface IRuleParam {
}
{code}
Both classes contained in the module jar and classes in the kjar should be loaded.
