I just ran into this question.
After updating the library in my application, I received the following error in the request:
Exception handling request to /path: java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonParser.hasToken(Lcom/fasterxml/jackson/core/JsonToken;)
Here's how I solved it:
jackson-core-2.5.1, wildfly-9.
, "jackson-core" /opt/wildfly/modules# grep -R 'jackson-core'
jboss-deployment-structure.xml WEB-INF:
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="com.fasterxml.jackson.core.jackson-core" />
<module name="com.fasterxml.jackson.core.jackson-databind" />

<module name="org.jboss.resteasy.resteasy-jackson2-provider" />
</exclusions>
