Jackson - java.lang.EnumConstantNotPresentException when deserialization with JsonTypeInfo.DEDUCTION

I have SpringBoot app (1.4.3.RELEASE). Recently I have upgraded Jackson (com.fasterxml.jackson.datatype, com.fasterxml.jackson.core) from 2.8.5 to 2.12.2 because of polymorphic subtype deduction feature. Everything works just fine on my local development environment during unit tests and also when I'm running app from IDE.

The problem occurs when I push my changes to build and deploy it on development environment, where app is deployed on Wildfly 21.0.2. (as a WAR archive). Calling ObjectMapper#readValue throws java.lang.EnumConstantNotPresentException (detailed stack below).

There are no enums used in objects which I'm deserializing and I have already checked through Wildfly management console, that there is correct version of Jackson on deployed app. Now I am a bit clueless. Any ideas?

Well, the problem was solved by explicit exclusion of Jackson related libraries in jboss-deployment-structure.xml file (as shown on code below). Without these exlusions Wildfly was forcing its own Jackson lib located in /wildfly/modules/system/layers/base/ path (e.g. wildfly/modules/system/layers/base/com/fasterxml/jackson/core/jackson-core) which is 2.10.5 for Wildfly 21.0.2. Wildfy is doing this regardless of specifing custom version in maven pom.xml. Also I wasn't able to find any mention about this "embedded" Jackson version in Wildfly through management console, so it was a bit pain to realize where is the problem. Maybe this will save someone else some time.

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.3">
    <deployment>
        <exclusions>
            <module name="com.fasterxml.jackson.core.jackson-core" />
            <module name="com.fasterxml.jackson.core.jackson-databind" />
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jdk8" />
            <module name="com.fasterxml.jackson.datatype.jackson-datatype-jsr310" />
            <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
            <module name="org.jboss.resteasy.resteasy-jackson2-provider" />
        </exclusions>
        <dependencies>
            <module name="jdk.unsupported"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>
